<p>A receiver capable of decoding a signal in accordance with the decoding ability of the receiver and the request about the signal to be decoded and a transmitter capable of performing such error correction and encoding are disclosed. Error-correcting/encoding means (11) of a transmitter (1) performs a predetermined error correction processing of digital transmitted data and a predetermined encoding processing of the data. The transmitted data may involve an error or errors while being transmitted through a transmission line (3). Decoding means (20) of a receiver (2) performs an error-correction processing and a decoding processing of the received data according to the degree of the error-correction processing and to that of the decoding processing. Preferably, the error-correcting/encoding means (11) encodes data by using systematic codes as an error-correction processing and an encoding processing about which the decoding means (20) can omit a simple processing or an error correction processing and decoding processing, or the error-correcting/encoding means (11) encodes data by using error-correcting codes, such as a multiplication sign, a connection sign, and turbo sign, the error characteristics of which are controllable by the number of repetitive processings by the decoding means (20).</p> |
