What do you mean by BER performance of Awgn channel?
In all digital modulation schemes, the bit error rate (BER) is an important metric. The BER is a direct measure of the possible data throughput under the given circumstances. That is, the smaller the BER, the better.
How is the BER of BPSK related to the SNR in an AWGN system?
For realizing that, the effect of noise is represented in the baseband with Gaussian random samples added to each signal sample. The signal to noise ratio (SNR) is varied to show the effect of SNR on BER. Finally the theoretical BER, i.e. Q(sqrt(2*SNR)) is also plotted to show the correctness of simulation.
Is there a significant difference in BER performance of PSK between the AWGN channel and rician channel?
The simulation model built for this research work, demonstrates that AWGN channel has better performance than Rayleigh and Rician fading channels.
What is the bit error probability for BPSK and QPSK?
The probability of error is identical for BPSK and QPSK because the BER has been measured in terms of signal to noise ratio per bit. in terms of signal to noise ratio per bit.
