Abstract:
1. A method for performing error correction for a synchronization frame, comprising: acquiring a receiver information sequence according to a frame structure of the synchronization frame sequence from a transmitter acquiring a syndrome sequence according to the receiver information sequence; acquiring an error pattern according to the syndrome sequence; and acquiring result of error correction according to the error pattern and the receiver information sequence, wherein the syndrome sequence is calculating the module-2 sum of four predetermined values in the receiver information sequence the error pattern is determining an index set, A(i)={j determining whether the number of bits with a value of 1 in the s determining that e determining that e i =0 when the number of bits with a value of 1 in the s j , s j . . . , s j in the syndrome sequence, =(s 0 , s 1 . . . s N−1 ) is less than or equal to half of total number of the bits, the acquiring the result of the error correction comprises: performing module-2 adding for the receiver information sequence, taking the acquired
