awgn channel Why dont you use the blocksets avaliable in Simulink, I am sure that there are blockset for AWGN which you can use easily. Simulink is very helpful more than matlab coding to simulate communications systems as well as if there is a certain function that you can't find in the Simulink blockset, you can create a matlab function for it and embed it as a blockset inside your model.

out = awgn(___,powertype) specifies the signal and noise power type as 'dB' or 'linear' in addition to the input arguments in any of the previous syntaxes. For the relationships between SNR and other measures of the relative power of the noise, such as E s /N 0, and E b /N 0, see AWGN Channel Noise Level. MATLAB: Issue with passing data through AWGN Channel I am trying to send QAM data through AWGN channel and I have 256 samples/symbol, I have the following code: The berawgn function returns the bit error rate (BER) and symbol error rate (SER) in an additive white Gaussian noise (AWGN) channel for uncoded data using various modulation schemes. The first input argument, EbNo , is the ratio of bit energy to noise power spectral density in dB ( E b / N 0 ). awgn matlab code Can anyone help me with this project?

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. The following examples use an AWGN Channel: QPSK Transmitter and Receiver and General QAM Modulation in AWGN Channel.

i am trying to do some simulation of AWGN channel. matlab has a function awgn(x,snr). what kind of snr does it use here? is it Eb/No (average bit energy/power spectral density)? If so, then i know the awgn has a PSD equal to No/2. does that psd in the snr term implies No/2?
