Abstract:
1. A transmission and reception system comprising a transmission device and, a receiving device, and a communication pathway between said transmission device and said receiving device, said transmission device comprising: (1) convolutional coding means for convolution-coding input data, and outputting convolution-coded data; (2) puncturing means for puncturing said convolution-coded data using puncturing patterns, and outputting punctured data; and (3) modulation/transmission means for modulating and transmitting said punctured data, and said receiving device comprising: (1) reception/demodulation means for receiving and demodulating a signal transmitted by said transmission device, and outputting demodulated data; (2) depuncturing means for depuncturing said demodulated data using said puncturing patterns used by said puncturing means, and outputting depunctured data; (3) combining means for combining said depunctured data, and outputting a result of combining; and (4) convolutional decoding means for convolution-decoding said result of combining, and outputting a decoded data, wherein said puncturing means provides a reference matrix for generating a plural form of said puncturing patterns having an identical puncturing rate, but respectively different block patterns.
