Method and system for bluetooth decoding

摘要

A system and method for Bluetooth(R) 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: $M_0=\sum _{n=0}^{14}\mathrm{abs}\left(\mathrm{RX}\left(n\right)\right),$ 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.
