Fuzzy Based power control system Using ANFIS and MIMO

To have the function measure the power of in before adding noise, … 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. View MATLAB Command.

The script implements the following steps: Given the target PSD, the total noise power is computed. Given the total power (equal to variance), the time-domain noise is generated.

I do have an equalizer in the system, I have tried turning it off altogether and performances get (of course) worse in both cases, but the Rice+awgn is still 1 dB better than awgn alone. I am trying to simulate a OFDM system with AWGN channel, 4QAM symbol in matlab.

y = awgn (x,snr)将白高斯噪声添加到向量信号x中。. 标量snr指定了每一个采样点信号与噪声的比率，单位为dB。. 如果x是复数的，awgn将会添加复数噪声。. 这个语法假设x的能量是0dBW。. y = awgn (x,snr,sigpower)和上面的语法相同，除了sigpower是x的能量，单位为dBW。.
