Rayleigh ber at high snr
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. In low s (t) Signal input Fixed Gain y (t) Signal Output WebJul 29, 2024 · Next, we varied the SNR levels to analyze how the SNR affected the covertness and the BER in Figure 11a,b. As expected, the CJ needs a higher PNR to fool the eavesdropper when the SNR is high. Furthermore, we observe that the BER slightly increases when the PNR increases and the BER is higher for a lower SNR.
