| 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.
