Is there a significant difference in BER performance of PSK between the Awgn channel and rician channel?
The performance of Rician fading channel is worse than that of AWGN channel and better than that of Rayleigh fading channel. Because Rician fading channel has higher BER than AWGN channel and lower than Rayleigh fading channel.
How AWGN affects the communication system?
AWGN is often used as a channel model in which the only impairment to communication is a linear addition of wideband or white noise with a constant spectral density (expressed as watts per hertz of bandwidth) and a Gaussian distribution of amplitude.

How is the BER computed for an AWGN channel?
The BER is computed for each Eb / N0 setting specified by input EbNo according to the modulation type specified by input modtype and related dependencies. Symbol error rate (SER) for uncoded data over an AWGN channel, returned as a scalar or vector.
How is symbol error rate calculated in AWGN?
Symbol error rate (SER) for uncoded data over an AWGN channel, returned as a scalar or vector. The SER is computed for each Eb / N0 setting specified by input EbNo according to the modulation type specified by input modtype and related dependencies.
What does Ber and Ser mean in berawgn?
Values in the output ber and ser vectors correspond to the theoretical error rate at the specified Eb / N0 levels for a Gray-coded signal constellation. For more information, see Analytical Expressions Used in berawgn Function and Bit Error Rate Analysis App.
What is the output Ber of the berawgn function?
The berawgn function returns the BER of various modulation schemes over an additive white Gaussian noise (AWGN) channel. The first input argument, EbNo, is the ratio of bit energy to noise power spectral density, in dB. If EbNo is a vector, the output ber is a vector of the same size, whose elements correspond to the different E b /N 0 levels.
