RESULTS AND ANALYSIS A.
Testing BER Bit Error Rate Performance
1. BPSK Modulation
The graph in the figure below shows the ratio of BPSK modulation when it is passed only through the course
AWGN channel, rayleigh fading channel alone and the combination of both channels. For BPSK modulation are
passed through AWGN channel and rayleigh fading BER values are joined its worst among the two other tests.

2. Modulasi QPSK
The picture below shows a comparison of chart testing QPSK modulation when passed only through the AWGN
channel only, rayleigh fading channel alone and the combination of both channels. For QPSK modulation BER
values are passed through AWGN channel and rayleigh fading is incorporated worst among the two earlier tests in
this test because its BER value at least as impaired as the SNR value addition.
