Patent ID: 7835263

Claim:
A communication device that carries out communication using N number of communication channels, N being an integer not less than 2, comprising: N number of demodulating units that demodulate receiving signals according to a modulation method used at a transmitting end; a trans-communication channel deinterleaving unit that receives a shuffled data series and carries out a second shuffling process on the shuffled data series, to regenerate an original data series, wherein at the transmitting end, the original data series undergoes an error correction encoding process to produce an encoded data series, the shuffled data series is generated by a first shuffling process, which is carried out by a communication device on a transmitting end, and which includes shuffling the encoded data series three-dimensionally in a time direction, a frequency-divided communication channel direction, and a space-divided communication channel direction, and the second shuffling process is a reverse of the first shuffling process; and M number of error correction decoding units that decode the original data series according to the error correction encoding process used at the transmitting end, M being an integer not less than 2.
