During transmission, a fold point is determined in which symmetric free channels are sufficient to transmit the signal.

A matched filter bank produces ratings for each of the possible three symbol modulating patterns in proportion to the likelihood that the combination in question may have produced the current but by now impaired input segment. While the three symbol window slides symbol-by-symbol over the input the successive hypothesis tests are not independent as each symbol is involved in three consecutive tests.

The same set of N sub-carriers is used for the fallback modes as for the normal mode. Since the same set of sub-carriers is used, the overall bandwidth is substantially constant, so alias filtering does not need to be adaptive. The Fourier transform operations are the same as for the normal mode. Thus fallback modes are provided with little hardware cost. In the fallback modes the increased guard time provides better delay spread tolerance and the increased symbol length provides improved signal to noise performance, and thus increased range, at the cost of reduced data rate. | 2012-06-28 |

A participant to replace the original moderator is identified and subsequently promoted to replacement moderator while maintaining the e-conference. Additionally, changing moderators during an e-conference is accomplished by creating a new conference bridge and transferring each participant to the new conference bridge. This method allows for a seamless transfer between moderators during an e-conference without the inconvenience of reconnecting. | 2012-06-28 |
20120163577 | METHOD AND SYSTEM FOR AUTOMATIC CONFERENCE CALL SESSION MIGRATION - Disclosed herein are methods, systems, and non-transitory computer-readable storage media for conference call session migration. The conference call session migration includes automatically configuring and establishing a target conference call session during a source conference call session; automatically converting session state and session history from a source format of the source conference call session to a target format of the target conference call session, and automatically connecting per-user clients to the target conference call session. For example, in response to a request from a session manger, the participants on the source conference call session are added to the target conference call session in order to add new media or other conferencing capabilities subject to network and server capabilities, user devices, user conferencing software, user location, user preferences, and policies. | 2012-06-28 |
20120163578 | System and Method for Providing Call-Back Options - A system and method for providing call-back options is disclosed. The method comprises receiving a call in a call routing system, providing at least one call-back option for a caller to receive a call-back, re-allocating resources in the call routing system based at least in part on the at least one call-back option, and calling the caller based on the at least one call-back option. The caller may specify a specific time, a relative time, or a time range when a call-back is preferred. The caller may also specify one or more telephone numbers in combination with the time preferences. The call-back may be initiated by a voice response unit (VRU) and additional call-back options may be presented to the customer who responds to the call-back. | 2012-06-28 |
20120163579 | Method and application server for obtaining the users' capability in third party call control - The present disclosure provides a method and an Application Server (AS) for obtaining user's capability in Third Party Call Control (3PCC), and the method comprises: when a user performs 3PCC, an AS stores the media information of the user; the AS performs media negotiation with the user according to the stored media information of the user. The application of the present disclosure solves the problem of the high failure probability of media negotiation caused by the current incorrect method for obtaining the user's media capability, and improves the utilization experience of users. | 2012-06-28 |
20120163580 | SOUND PROCESSING APPARATUS, METHOD, AND PROGRAM - A sound processing apparatus includes: a sound output unit which outputs sound based on a first sound signal as first sound processing when execution of the first sound processing is instructed; a sound collecting unit which generates an echo signal by collecting surrounding sound; a filtering unit which performs filtering process with an adaptive digital filter on the first sound signal and generates a pseudo echo signal; a subtracting unit which removes a sound component, which is output from the sound output unit and reaches the sound collecting unit, from the echo signal by subtracting the pseudo echo signal from the echo signal to generate a residual signal; an updating unit which updates the adaptive digital filter based on the residual signal and the first sound signal; and an update resolution control unit which controls the resolution at which the adaptive digital filter is updated by the updating unit. | 2012-06-28 |
20120163581 | ELLIPTIC CURVE CRYPTOGRAHY WITH FRAGMENTED KEY PROCESSING AND METHODS FOR USE THEREWITH - A cryptography module includes a key store having a plurality of storage locations for storing a private key as k key fragments. One or more crypto-processing segments each operate based on corresponding ones of the k key fragments to process a message in accordance with elliptic curve digital signature algorithm (ECDSA) to produce a signed message. | 2012-06-28 |
20120163582 | DATA ENCODING AND DECODING APPARATUS AND METHOD THEREOF FOR VERIFYING DATA INTEGRITY - A data encoding apparatus for verifying data integrity by using a white box cipher includes: an encoding unit for encoding content by using a white box cipher table; and an arithmetic logic unit for performing an arithmetic logic operation on the white box cipher table and content information to output an encoded white box cipher table. The arithmetic logic operation is an exclusive OR operation. The content information is license information of the content or hash value of the license information of the content. | 2012-06-28 |
