Abstract
OFDM transmitting output equipment, radio frequency band pass filter (BPF) and nonlinear AM-PM amplifier, are simulated by using one of communication system design support tool. It is confirmed that BPF characteristics do not affect BER (Bit Error Rate)-C/N performance owing to pilot signal equalization, if FFT size is more than 2048 (number of carriers is 1536). Effects of several AM-PM amplifiers on BER-C/N performance and transmitting spectrum are calculated.
