y = awgn(x,snr) adds white Gaussian noise to the vector signal x. The scalar snr specifies the signal-to-noise ratio per sample, in dB.
y = db2pow(ydb) returns the corresponding power value y for a given decibel (dB) value ydb. Note that ydb = 10*log10(y).
ydb=pow2db(y) returns corresponding decibel value ydb for given power value y. The relationship between power and decibel is ydb=10*log10(y)
