The minimum average signal-to-noise ratio (SNR) per bit required for error-free transmission over a fading channel is derived, and is shown to be … Webthe level of background noise. The higher the ratio, the less obtrusive the background noise is. SNR = (Psignal / Pnoise) = (Asignal / Anoise) 2 While considering effect of BER on SNR, results shows that the BER performance is improved dramatically in low SNR, while not in high SNR.
