ESTIMATION OF BIT ERROR PROBABILITY IN UNCODED FHSS

Spread spectrum technology has emerged into the commercial market place for improving business transactions. frequency hopping is the easiest spread spectrum modulation to use. any radio with a digitally controlled frequency synthesizer can, theoretically, be converted to a frequency hopping radio. the minimum frequency switching rate usable in a frequency hopping system is determined by the type of information being sent, its rate and the amount of redundancy used. this paper discusses the probability of error of uncoded frequency hopping with m-ary frequency shift keying (mfsk) and the system model designed in this paper shown that the bit error rate is decreasing by sending more chips for a bit. the simulation results have proved that frequency hopping is left unchanged and directly modulates a carrier of varying frequency and is not so sensitive to such interferers.
