This paper propose a design and simulation of Amplitude Shift Keying (ASK ) 31 channel frequency hopping spread spectrum (FH/SS) transceiver system.The proposed design is implemented using Matlab/Simulink package.There are many available synchronization techniques that can be used in frequency hopping spread spectrum (FH/SS) miracle academy clothing transceiver system most of these techniques require complex search operation and hence need complex hardware.In this paper a contiguous 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.

This designed bank of digital filters is used as a new, simple and efficient approach for synchronization of the system.This proposed system can be used to transmit and receive 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 (HF) band, 18.6 MHz (3-21.6 MHz).

Two orange zinger tomato models of jamming: multi-tone jamming (MTJ) and hopper jamming (HJ) were designed and simulated with and without the presence of Additive White Gaussian Noise (AWGN) to test the proposed design system.The obtained results proved that the proposed system passed these tests successfully.
