In order to transmit and receive not less than a binary digital signal using a code table in which chaotic map is used and an independent component analysis, a transmitting device (121) and a receiving device (141) of a communication system (101) use the same chaos function T(.) and the same applying function A(., .) to generate and hold a corresponding table that makes a sequence of a predetermined length correspond to each of bit sequences of a predetermined length as a code by using a code table generating device (161). The transmitting device (121) modulates a code corresponding to a bit sequence to be transmitted for transmission and the receiving device (141) performs an independent component analysis of signals received by a plurality of antennas to identify a signal of an analysis result with the maximum correlation with a code contained in the corresponding table as a signal transmitted from the transmitting device (121) and outputs a bit sequence corresponding to a code with the maximum correlation with the identified signal of the analysis result in the code table as a transmitted signal.
