摘要： RF communications received by a wireless terminal from a servicing base station are used to determine the BEP. These RF communications may be in the form of RF bursts that are part of a data frame. The signal to noise ratio (SNR) of the RF burst is determined and a sequence of soft decisions from the RF burst are extracted. The SNR maps to an estimated BEP based upon the modulation format and coding scheme of the RF burst. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). When the decoding is unsuccessful, the BEP is estimated only upon the estimated BEP derived from the SNR. Otherwise, both the estimated BEP and RBER may be used to determine the BEP.

摘要： Certain aspects of a method and system for a delay locked loop for a rake receiver are disclosed. Aspects of one method may include normalizing a signal power of a first control channel based on a threshold value. A sampling time associated with at least one or more of the following: the first control channel, a second control channel, an on-time control channel, and a data channel, may be adjusted based on a comparison between the normalized signal power of the first control channel and a signal power of the second control channel. The second control channel may be delayed with respect to the first control channel by a particular time period. The first and second control channels may be common pilot control channels (CPICHs). The combined signal power of the first control channel may be normalized based on said threshold value.

Aspects of the method may comprise up-sampling a number of digital audio signals and converting the up-sampled digital audio signals to a common data rate prior to mixing. The digital audio signals sampling rates may be converted utilizing half-band interpolators. The up-sampling may also utilize infinite impulse response interpolators. A portion of the up-sampled digital audio signals may have a common data rate. The common data rate may be determined by the number half-band interpolators utilized. Distortion in the digital audio signals may be compensated utilizing an infinite impulse response filter or a finite impulse response filter.

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： The present invention provides methods and systems that generate symbol delay times. By receiving a communication signal using a plurality of antennas, a set of respective communication channels can be characterized. The characterized channels can be then used to determine sets of forward-time delays and time-reverse delays using a minimum-mean-square-error technique. By selecting the set of delays that can provide a lower mean-square-error in an equalizer, symbol estimation can be improved as compared to a system that only estimates delays in a single temporal direction.

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.
