摘要： A system and method for Bluetooth® decoding is disclosed and may include calculating a remainder value based on a received bit sequence and a generator polynomial for a corresponding transmitted Bluetooth bit sequence. Remainders may be generated from known error vectors and the generator polynomial. The generated remainders may result in at least a portion of the known error vectors corresponding to the generator polynomial. A codeword may be selected that may correspond to the calculated reminder value that matches one of the generated remainders. The generated remainders may be stored in a look-up table. An initial metric value may be calculated utilizing the following equation: M 0 = ∑ n = 0 14 abs ( RX ( n ) ) , where RX(n) may include the received bit sequence. The codeword with a metric value equal to M0 may be selected, if the calculated remainder value is equal to 0.

摘要： Aspects of a method and system for an improved cellular diversity receiver are described. Aspects of the system may include circuitry that enables generation of an initially decoded output bit sequence by a first frame process for a received bit sequence for a plurality of received multipath signals. The first frame process may utilize redundancy based decoding, which imposes at least one physical constraint during the decoding, which may be performed by a decoding algorithm.

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： A method and system for decoding control data in GSM-based systems using inherent redundancy and physical constraints are presented. At least one estimated GSM-based bit sequence may be selected by performing searches that start from trellis junctions determined by the decoding algorithm. The estimated bit sequences may be selected based on corresponding redundancy verification parameters. At least one physical constraint test may be performed on the selected estimated GSM-based bit sequences to select a decoded output GSM-based bit sequence. A multilayer decoding process may comprise a burst process and a frame process. Results from a first burst process may be utilized to generate a decoded GSM bit sequence in the frame process. The frame process may utilize redundancy information and physical constraints to improve the performance of a decoding algorithm.

At least a first weighting factor may be determined from the corresponding plurality of scaling factors.
