Abstract: Provided is a pattern division multiple access (PDMA) communication system based on optimal frequency-hopping patterns, which includes a transmitter and a receiver. The transmitter modulates an input baseband signal into a modulated signal, and then converts the modulated signal into a signal that hops in frequency according to the optimal frequency-hopping pattern. The receiver reverts the received frequency-hopping signal to an output modulated signal using an optimal frequency-hopping pattern same as that of the transmitter, and then demodulates the modulated signal into a baseband signal. The optimal frequency-hopping patterns are obtained by applying two-dimensional cyclic shift to a Golomb Costas array constructed based on an extension field, and thus are frequency-hopping patterns with ideal autocorrelation and cross-correlation properties.
