| 20150230175 | MULTI-ACCESS COMMUNICATION SYSTEM - A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages. | 08-13-2015 |
| 20150245341 | Channel Allocation in a Communication System - Methods and systems are described which provide solutions for determining how to allocate terminals to slots in order to maximise communication system performance in the case where there is no feedback channel between a multiuser satellite receiver and terminals within the field of view. Terminals operate independently of each other and choose transmission slots based upon the geographic position of the terminal. Terminals can be programmed with a slot selector to choose slots according to some deterministic or non deterministic function of the current position. A slot plan database may be used to assist in efficient slot selection. Regular and irregular grid based allocation methods are described, that reduce the likelihood that too many terminals transmit using the same slot within the field of view. Satellite induced Doppler effects can be utilised be further increase slot re-use and to improve allocation of slots so that the receiver sees an approximately uniform distribution of frequencies over the frequency band to improve system throughput. The approaches described herein greatly reduce or eliminate the probability of failure at the receiver, which has numerous implementation advantages such as reduced cost, complexity, and power consumption. | 08-27-2015 |
| 20150256247 | COMMUNICATION SYSTEM AND METHOD - A communication system is disclosed. In an embodiment, the communication system includes a user node for receiving data from a remote application program, the data including message data for communication to a central application program operatively associated with the remote application program; plurality of geographically distributed gateway nodes; one or more access nodes for receiving the message data from the user node via a first communications interface, and communicating the message data via a second communications interface to one or more of the plurality of geographically distributed gateway nodes; and a hub for communicating with the one or more of the plurality of geographically distributed gateway nodes to receive the message data for communication to the central application. | 09-10-2015 |
| 20150312073 | Carrier Phase and Amplitude Estimation for Phase Shift Keying Using Pilots and Data - A least squares estimator of carrier phase and amplitude in a receiver in a communication system using a phase shift keying modulation scheme that uses both known pilot symbols and unknown data symbols is described. That is, the method exploits knowledge of pilot symbols in addition to the unknown data symbols to estimate carrier phase and amplitude. Further, an efficient recursion based estimation method is described that only requires O(L. log L) arithmetic operations where L is the number of received signals. This method uses the M-Ary rounded phase offsets to sort the data symbols and this sorted order is used to recursively calculate candidate values in an optimisation process. Simulation results show that the estimation methods Using data and pilot symbols outperform estimation methods using only data symbols (ie non-coherent detection methods). Further, the system can be used for systems using multiple M-ary phase shift keying digital modulation schemes. | 10-29-2015 |

| 20110131122 | BEHAVIORAL BASELINE SCORING AND RISK SCORING - Embodiments of the present invention relate to systems, apparatus, methods and computer program products for integrated risk management. More specifically, embodiments of the present invention provides for determining one or more behavioral baseline scores, each score associated with one or more behaviors and based at least in part on financial institution data from multiple financial institutions. The behavioral baseline score defines a normal risk or baseline behavior for a customer, a customer segment or customer population. Further, the invention provides for monitoring at least the financial institution data to determine deviations from the behavioral baseline score(s) and generating and initiating communication of risk score alerts and/or behavioral baseline deviation alerts based on predetermined behavioral baseline deviations. Additional embodiments provide for determining a risk score based on risk patterns associated with financial institution data and, in some embodiments, non-financial institution data. | 06-02-2011 |
