摘要： Multi-channel noise suppression systems and methods are described that omit the traditional delay-and-sum fixed beamformer in devices that include a primary speech microphone and at least one noise reference microphone with the desired speech being in the near-field of the device. The multi-channel noise suppression systems and methods use a blocking matrix (BM) to remove desired speech in the input speech signal received by the noise reference microphone to get a “cleaner” background noise component. Then, an adaptive noise canceler (ANC) is used to remove the background noise in the input speech signal received by the primary speech microphone based on the “cleaner” background noise component to achieve noise suppression. The filters implemented by the BM and ANC are derived using closed-form solutions that require calculation of time-varying statistics of complex frequency domain signals in the noise suppression system.

摘要： Methods and systems for decoding control channels using repetition redundancy may include generating enhanced soft bits by combining soft bits generated from the two GSM SACCH blocks. Combining may comprise averaging soft bits in one GSM SACCH block and corresponding soft bits from the other GSM SACCH block. Information in one GSM SACCH block may be repeated in the other GSM SACCH block. If repetition is detected, the enhanced soft bits may comprise enhanced soft bits for at least a portion of level 1 region and level 3 region of the GSM SACCH block. Otherwise, the generated enhanced soft bits may comprise enhanced soft bits for at least a portion of level 3 region of the GSM SACCH block.

摘要： Various aspects of a method and system for adaptive multi rate and measurements adaptation may include a processor that enables computation of at least one signal level measurement for at least one received signal. The processor may enable cancelling of interfering signals received in addition to the received signal based on processing of a received bit sequence using a first burst process operation (BP) in a first decoding algorithm that utilizes SAIC operations. The processor may also enable cancelling of noise signals received in addition to the received signal based on processing the received bit sequence using a second BP operation that utilizes redundancy and imposes a physical constraint during decoding. The processor may also enable adjustment of the computed at least one signal level measurement.

摘要： A method and system for decoding SACCH control channels in GSM-based systems with partial combining using weighted SNR may comprise combining least one weighted bit of a GSM slow associated control channel (SACCH) frame with at least one weighted bit of a subsequent GSM SACCH block based on burst signal to noise ratios (SNRs) of the GSM SACCH block and the subsequent GSM SACCH block. The burst SNR may be determined from a mid-amble of the GSM SACCH block and its subsequent GSM SACCH block. The burst SNRs of the GSM SACCH block may be translated to a corresponding plurality of scaling factors. At least a first weighting factor may be determined from the corresponding plurality of scaling factors. At least one weighted bit of the GSM SACCH block is determined utilizing the determined first weighting factor.

摘要： Aspects of a method and system for decoding single antenna interference cancellation (SAIC) and redundancy processing adaptation using frame process are provided. A receiver may decode video, voice, and/or speech bit sequences based on a first decoding algorithm that may utilize data redundancy and that may impose physical constraints. The receiver may also decode a bit sequence based on a second decoding algorithm that utilizes SAIC. The first and second decoding algorithms may be adapted to perform in parallel and a decoded received bit sequence may be selected based on a redundancy verification parameter. The first and second decoding algorithms may also be adapted to be performed sequentially where the subsequent decoding operation may be conditioned to the initial decoding operation. Moreover, either the first or the second decoding algorithm may be selected for decoding the received bit sequence. The selection may be based on noise and/or interference measurements.
