Abstract:
1. A method of symbol interleaving, comprising: dividing modulation symbols into a plurality of symbol groups; generating a symbol group sequence y with a length of M, wherein the symbol group sequence comprises the plurality of symbol groups; and performing the symbol interleaving on the symbol group sequence y according to a symbol interleaving sequence to obtain a sequence w, wherein the symbol interleaving sequence is a sequence generated by: defining a sequence S(i) with the length of M and a value domain of {0, 1 . . . N−1}; and respectively substituting element values in the sequence S(i) with the numerical values of corresponding disjoint sequences, wherein each of the disjoint sequences, numbered {0, 1, . . . , N−1}, is distributed to the corresponding elements in the sequence S(i), where the N disjoint sequences are formed by numerical values from an integer set {0, 1, . . . , M−1}, and Hamming correlations of the sequence S(i) are smaller than or equal to a predefined threshold.
