This research was conducted FHMA (Frequency Hopping Multiple Access) standard using Labview. FHMA was developed in Israel in the spectral efficiency. The main objective of this research is to emphasize the performance of the communication system of FHMA paper. FHMA have good radio features that provide full radio capacity, covering the trunking and untargeted mobile phone, with a choice of services including packet mode, short message services and voice. FHMA is compatible with a wide range of additional services, and can be used as for government, emergency services, transportation and military applications.

The impact of timing and frequency offsets, as well as the composite effects of multitone jamming (MTJ) and partialband noise jamming (PBNJ) on bit-error rate (BER) performance of an fast frequency-hopped (FFH) system are investigated. Both the desired signal and MTJ are assumed to undergo frequency-selective Rayleigh fading. Analytical BER expressions for the FFH maximum-likelihood (ML) receiver are derived and validated by simulation results. Numerical results show that the timing and frequency offsets significantly degrade performance of the FFH ML receiver. It is also shown that the proposed ML receiver can suppress the MTJ more effectively than the PBNJ.Index Terms-Fast frequency-hopped, timing offset, frequency offset, multitone jamming, partial-band noise jamming, maximum-likelihood receiver, frequency-selective Rayleigh fading.
