A Novel Receiver for FHMA Systems

A novel FH/MFSK receiver with additional partial correlators is proposed by means of side information for asynchronous frequency-hopping multiple-access (FHMA) systems in the presence of Rayleigh fading. Performance analysis is carried out and compared for both the novel and conventional receivers. One hop per symbol and Reed-Solomon (RS) coding are used in the FHMA systems. It is shown that the novel receiver performs much better than the conventional receiver for a wide range of signal to noise ratio. The capacity of the FHMA system with novel receivers is almost as twice as that of the system with conventional receivers
