RAYLEIGH CHANNEL AND AWGN CHANNEL Abdul Haq N 1, Rajani Katiyar * and Padmaja K V2 BER results obtained using Matlab simulation scripts show, good agreement with the derived theoretical results. With Binary Phase ShiftE b / N 0 vs BER for BPSK over Rayleigh Channel and AWGN Channel.

In this lab, you will generate an antipodal symbol stream and send it through an AWGN channel. Since only discrete-time can be simulated in MATLAB, we will assume that the signal has passed through an D/A converter at the transmitter and a A/D converter at the receiver. This example shows how to model OFDM transmitter, additive white Gaussian noise (AWGN), and OFDM receiver hardware algorithms in MATLAB® as steps toward developing a Simulink® implementation for hardware. An AWGN channel adds white Gaussian noise to the signal that passes through it. You can create an AWGN channel in a model using the comm.AWGNChannel System object™, the AWGN Channel block, or the awgn function. An AWGN channel adds white Gaussian noise to the signal that passes through it.

For the relationships between SNR and other measures of the relative power of the noise, such as Es / N0, and Eb / N0, see AWGN Channel Noise Level.

In this post, we will use MATLAB to simulate the capacity, outage and BER performance of a two user NOMA network by following a more realistic model namely, Rayleigh fading model. The SNR and Input signal power, referenced to 1 ohm (watts) of AWGN Channel Block are 20 dB and 1 watts respectively. When the power of ACPR is around 20 dB , which is equal to the SNR we set in AWGN Channel Block, the Channel Powers showed in Spectrum Analyzer is around -20 dB , which I expect to be around 30 dB for referencing to 1 watts should result in -30 dB .
