Abstract
A communication system comprises a transmitting apparatus and receiving apparatus for transmitting/receiving a N-ary signal, based on a prime number exceeding 2, inclusive of an efficient error correction system. The transmitting apparatus includes a binary to N-ary converting unit for converting a binary transmit signal into an N-ary signal, as an information sequence, where the N of the N-ary number is a prime number exceeding 2, an encoding unit for generating a transmit sequence, comprised of BCH code on a Galois field with the number of elements being a prime number exceeding 2, and a multi-level modulating unit for multi-level modulating the transmit sequence and for transmitting the multi-level modulated transmit sequence to a receiving apparatus. The receiving apparatus includes a demodulating unit for demodulating the received signal from the transmitting apparatus and for producing a multi-leveled received sequence, with the multi-level of the received sequence being a prime number exceeding 2, a decoding unit for decoding the received sequence by a decoding method for a BCH code on a Galois field with the number of elements being a prime number exceeding 2, and a N-ary to binary conversion unit for producing a decoded binary signal from the N-ary signal as a decoded sequence.
