be mobile, Doppler frequency shift is considered in the channel. Four defined protection levels in mode one were simulated and the results are shown in Figure 2. The desired Bit Error Rate (BER) in the standard is about 2*E-4 [6]. For example, in mode one, protection level two and frequency Doppler of 30Hz, the desired BER is achieved for SNRs
