A communication system (101), which uses a primitive root "q" of a prime number "p",uses b[k] = (1, exp(2Ài×q 0+k /p), exp(2Ài×q 1+k /p), ..., exp(2Ài×q (p-2)+k /p)) for each value of an integer k=0, 1, ..., (p-2), "p" number of p-dimensional vectors b[i] each defined by b[p-1] = (1, 1, 1, ..., 1), and their conjugate complex vectors c[i]. A transmitting device (111) converts a signal to be transmitted into a parallel form, calculates the inner products between the parallel signals and the vectors b[i] respectively, inserts guard intervals to convert them into a serial form and transmits the serial signal. A receiving device (131) eliminates the guard intervals from the received signal, synchronizes with the signal, converts the signal into a parallel form, calculates the inner products between the parallel signals and the vectors c[i] respectively, converts the signals into a serial form to obtain the signal that has been transmitted. |
