Design of ask 31 channel frequency hopping spread spectrum transciever system using banks of noncontiguous band pass filters(Article)

Abstract

There are many available synchronization techniques that can be used in frequency hopping spread spectrum (FH/SS) transceiver system most of these techniques require complex search operation and hence need complex hardware. In this paper noncontiguous (NC) parallel digital band pass filter (BPF) banks for 31 channel FH/SS transceiver system has been designed and implemented successfully in real time using Matlab /Simulink. The proposed system is simple and efficient approach for synchronization of FH/SS transceiver. It can be used to transceive digital information with a data rate of 160 k bit /sec for frequency hopping rate of 160 k hop/sec and spread the transmitted data in the high frequency band, (3-12.6 MHz). Finally the proposed design was tested under sever jamming conditions using multi-tone jamming (MTJ) and hopper jamming (HJ) in the presence of Additive White Gaussian Noise (AWGN). The results obtained were vey encouraging.
