Abstract
A noncoherent, bandwidth efficient modulation scheme is proposed for frequency hopping multiple access (FH-MA) networks. The proposed modulation scheme is a combination of noncoherent M-ary amplitude shift keying (MASK) and orthogonal frequency division multiplexing (OFDM). Using this modulation scheme will minimize the required data bandwidth. When compared to the conventional noncoherent scheme used in FH systems, i.e., M-ary frequency shift keying (MFSK), the number of frequency slots available to the users will increase significantly for a fixed spread spectrum (SS) bandwidth. Therefore, the effect of the multiple access interference (MAI) will be reduced. Simulations and theoretical results have shown that significant MAI reduction can be achieved.
