概要

A channel coding which combines convolutional coding and M-ary PSK/orthogonal multi-carrier (MPSK/OMC) transmission is proposed. A coding gain is achieved without sacrificing the data rate or occupying extra bandwidth. The proposed coding formula is that the information data bits of bit interval Ts are serial to parallel converted to P parallel branches where each branch has a bit interval T_p=PT_s. The data bits of the parallel branches are encoded through a rate nP/ (n + 1) (2P - 1) convolutional encoding process and the total (n + 1) (2P - 1) symbol of the encoder output is transmitted by 2P- 1 OMCs where each carrier is modulated by MPSK/OMC (M=2^<n+1>). Following performance analysis of a coding form using rate P/ (2P - 1) convolutional encoder and BPSK/OMC modulation, a general channel coding combining convolutional coding and MPSK/OMC modulation is discussed.
