Modelling RF Power Amplifier to Study its Non Linear Effects on RF Communication System, with BER as a Performance Measure

摘要

The simulation has been done in MATLAB 7.7.0471. In the simulator the transmitter transmits bits at a given data rate. These bits are then modulated using multilevel modulation schemes. Then the modulated bits are transmitted through a channel with AWGN. They are then demodulated and sent to the receiver. The received bits are then compared with the sent bits and then BER is evaluated. This BER depends on the SNR of the signal. The following figure shows a block diagram of different elements in the simulator ¨
