What is BER performance in fading channels?
The berfading function returns the bit error rate (BER) and symbol error rate (SER) over a Rayleigh or Rician fading channel for uncoded data using a specified modulation scheme. The first input argument, EbNo , is the energy per bit to noise power spectral density ratio (Eb/N0) in dB.
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.
Which modulation is better in Rayleigh Channel Why?
M-QAM modulation schemes are preferred because in this scheme more than one bit can be grouped and transmit at a time, which is very effective for band limited channels.
What is Rayleigh fading and how it affects the channel performance?
Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communication channel) will vary randomly, or fade, according to a Rayleigh distribution — the radial component of the sum of two uncorrelated Gaussian random variables.
