20090150156 | SYSTEM AND METHOD FOR PROVIDING A NATURAL LANGUAGE VOICE USER INTERFACE IN AN INTEGRATED VOICE NAVIGATION SERVICES ENVIRONMENT - A conversational, natural language voice user interface may provide an integrated voice navigation services environment. The voice user interface may enable a user to make natural language requests relating to various navigation services, and further, may interact with the user in a cooperative, conversational dialogue to resolve the requests. Through dynamic awareness of context, available sources of information, domain knowledge, user behavior and preferences, and external systems and devices, among other things, the voice user interface may provide an integrated environment in which the user can speak conversationally, using natural language, to issue queries, commands, or other requests relating to the navigation services provided in the environment. | 06-11-2009 |
20120101809 | SYSTEM AND METHOD FOR DYNAMICALLY GENERATING A RECOGNITION GRAMMAR IN AN INTEGRATED VOICE NAVIGATION SERVICES ENVIRONMENT - The system and method described herein may dynamically generate a recognition grammar associated with a conversational voice user interface in an integrated voice navigation services environment. In particular, in response to receiving a natural language utterance that relates to a navigation context at the voice user interface, a conversational language processor may generate a dynamic recognition grammar that organizes grammar information based on one or more topological domains. For example, the one or more topological domains may be determined based on a current location associated with a navigation device, whereby a speech recognition engine may use the grammar information organized in the dynamic recognition grammar according to the one or more topological domains to generate one or more interpretations associated with the natural language utterance. | 04-26-2012 |

20120109753 | SYSTEM AND METHOD FOR PROVIDING ADVERTISEMENTS IN AN INTEGRATED VOICE NAVIGATION SERVICES ENVIRONMENT - The system and method described herein may provide advertisements in an integrated voice navigation services environment. In particular, one or more advertisements may be identified based on affinities among a current location associated with a navigation device and shared knowledge and information used to interpret natural language utterances that relate to a navigation context, wherein the one or more advertisements may then be presented via a multi-modal output. As such, the shared knowledge and the information relating to the navigation context may provide the system and method with dynamic awareness relating to context, available information sources, domain knowledge, and user behavior and preferences, among other things, which may be used to deliver targeted and contextually relevant advertisements in the integrated navigation services environment. | 05-03-2012 |

20150073910 | SYSTEM AND METHOD FOR PROVIDING ADVERTISEMENTS BASED ON NAVIGATION-RELATED PREFERENCES - Advertisements may be provided based on navigation-related preferences. In certain implementations, a current location associated with a user may be obtained. One or more navigation-related preferences associated with the user may be obtained. An advertisement may be determined based on the current location and the navigation-related preferences. The advertisement may be provided for presentation to the user. In some implementations, a directional proximity of the user to a location associated with the advertisement may be determined. The advertisement may be determined (or selected for the user) based on the directional proximity and the navigation-related preferences. | 03-12-2015 |
20150095159 | SYSTEM AND METHOD FOR PROVIDING SYSTEM-INITIATED DIALOG BASED ON PRIOR USER INTERACTIONS - In certain implementations, a system-initiated dialog with a user may be provided based on prior user interactions. In an implementation, context information determined based on one or more prior interactions of the user with the system may be obtained. A dialog-initiation opportunity may be detected based on the context information. A natural language dialog with the user may be initiated based on the dialog-initiation opportunity. In an implementation, the one or more prior interactions of the user may comprise one or more prior conversations between the user and the system. At least one of the one or more prior conversations may, for example, comprise a natural language utterance of the user and a natural language response of the system to the natural language utterance. | 04-02-2015 |

20120307939 | ESTIMATION OF CHANNEL IMPULSE RESPONSE IN A COMMUNICATION RECEIVER - Embodiments herein provide using extreme value theory (EVT) as a diagnostic to decide which taps are significant. In the low SINR scenario, embodiments herein also provide the following options; i) Fix the model order to a finite value smaller than the model order assumed for the initial CIR estimate. In the case of OFDM based systems, the model order of the CIR is fixed to a value much smaller that the cyclic prefix length. ii) Use the EVT based method to detect significant tap locations and only keep those tap locations such that the CIR length is again restricted to a value smaller than the model order of the initial channel estimate. | 12-06-2012 |
20130215826 | Robust Channel Estimation of OFDM Systems - A system and method for estimating a channel in wireless communication systems using Orthogonal Frequency Division Multiplexing (OFDM). From the received OFDM symbols, Maximum Likelihood (ML) estimate of the channel frequency response is obtained at the pilot locations. A hypothesis test is performed on the ML estimates and the outcome of the hypothesis test is used to decide a shrinkage target. Biased estimation methods are used to shrink the ML estimates towards the shrinkage target to obtain better estimates of the channel frequency response at the pilot locations and these estimates are interpolated using a Filter to get a set of complete estimates of the channel over the resource block. The Filter is an Empirical Weiner Filter or a robust 2D-MMSE filter and the biased estimation is done using either a James-Stein (JS) estimator or a shrinkage estimator or an empirical Bayes estimator. | 08-22-2013 |

20150229435 | ADAPTIVE LINK ADAPTATION SYSTEM AND METHOD - The embodiments described herein provide a method and system for improve link adaption performance in wireless networks. The method for modifying the MCS index for transmission using a computed offset is provided. The offset is calculated based on HARQ feedback of transmissions. A transition probability matrix with plurality of MCS indices is used for selecting the MCS index for transmission based on the highest probability of transition. A pattern sequence of MCS indices is formed and the presence of the pattern is determined in the history of the HARQ transmissions. The frequency of the pattern presence is also determined and the MCS index is selected for the HARQ transmissions. A frequency database of MCS indices is built using source encoding techniques. The transition probabilities that are estimated from the frequency database along with a cost function associated with each MCS index will be used to compute next MCS index. | 08-13-2015 |
