1. A wireless communication method implemented in a communication system, comprising:

  • receiving a data sequence to be permuted;

    obtaining information associated with the data sequence to be permuted, the information containing at least a length of the data sequence and a sampling spacing for permuting the data sequence;

    identifying a first portion of the data sequence having a first number of adjacent data items, and a second portion of the data sequence having a second number of adjacent data items;

    accessing the first number of data items from the first portion at the sampling spacing;

    placing the accessed first number of data items into a predetermined number of sub-blocks included within a permuted data sequence to be generated based on the received data sequence;

    inserting each of the second number of data items into an end position of one of the sub-blocks within the permuted data sequence; and

    outputting the permuted data sequence.
