# 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 Es / N0, and Eb / N0, see AWGN Channel Noise Level.

Then demodulate, decode, and count errors. Create an LDPC encoder and decoder pair. Run the command by entering it in the MATLAB Command Window. Web browsers do not support MATLAB commands. In the top link, the AWGN channel block is set to provide a coded Eb/No of 8 + 10log10(4/7) dB, where 4/7 is the code rate. This accounts for the fact that the coded Eb/No is always lower (by a factor of the code rate) than the uncoded Eb/No.

This comes from the fact that the average symbol energy for 4-QAM is E s = 2. The comm.AWGNChannel expects the input signal to have unit power by default (expects Signal Power = 1, but by multiplying by sps you ended up setting Signal Power = 2 ( = E s) ).

The comm.AWGNChannel expects the input signal to have unit power by default (expects Signal Power = 1, but by multiplying by sps you ended up setting Signal Power = 2 (= E s)). There is a property SignalPower which needs to be set, see the documentation page (https://uk.mathworks.com/help/comm/ref/comm.awgnchannel-system-object.html). AWGN.

I've looked around quite a bit, but can't get a solution for simulating a binary asymmetric channel in matlab. I am supposed to simulate a BSC (binary symmetric channel) as well as a asymmetric cha 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 Matlab code to plot BER of QPSK under AWGN channel Matlab code to plot BER of QPSK under AWGN channel Matlab code to analyze constellation of QPSK and π Robust Control, Part 1: What Is Robust Control?
