ENCODING METHOD

摘要

At a transmission node, at least part of control information is divided into M (M: a natural number) control information blocks of an N-bit length (N: a natural number of 1 to 7), and each control information block i (i = 1 to M) is given a control information parity of a predetermined (8 to N) bit length so that it is encoded by the predetermined control information bit array into M control information codes of a length of 8 bits and is subjected to a control information transmission processing. Here, the control information parity and the control information bit array are such that the humming distance of each of the control information codes is at least d (d: a natural number of 2 to 8) and such that the humming distance of each of the codes of a control information 10B is at least D (D: a natural number of 2 to 10). At a reception node, the control information code is divided into a control information block and a control information parity, a parity test is made, and a detected error, if any, is error-processed.
