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: <maths id="MATH-US-00001" num="1"> <MATH OVERFLOW="SCROLL"> <MROW> <MROW> <MSUB> <MI>M</MI> <MN>0</MN> </MSUB> <MO>=</MO> <MROW> <MUNDEROVER> <MO>∑</MO> <MROW> <MI>n</MI> <MO>=</MO> <MN>0</MN> </MROW> <MN>14</MN> </MUNDEROVER> <MO></MO> <MSTYLE> <MTEXT> </MTEXT> </MSTYLE> <MO></MO> <MROW> <MI>abs</MI> <MO></MO> <MROW> <MO>(</MO> <MROW> <MI>RX</MI> <MO></MO> <MROW> <MO>(</MO> <MI>n</MI> <MO>)</MO> </MROW> </MROW> <MO>)</MO> </MROW> </MROW> </MROW> </MROW> <MO>,</MO> </MROW> </MATH> </MATHS> 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.
