## BER in OFDM systems

hi matlabers, i am trying to compute ber in ofdm but did not get the curve that i look for.anyone can help me?this is my code.. dataType = '16qam'; % Modulation format. totalSubcarriers = 1024; % Number of total subcarriers. numSymbols = 16; % Data block size. Fs = 5e6; % System bandwidth. Ts = 1/Fs; % System sampling (...)

## 16QAM theoretical BER under Rayleigh Fading

Hi all... I am simulating QAM signal in Rayleigh Fading environment in matlab... I want to compare the ber with theoretical ber... If in AWGN, theoretical ber of 16qam is given: ber_th=(3/8)*erfc(sqrt((2/5)*SNR))-(9/64)*(erfc(sqrt((2/5)*SNR)))^2 I dont know how to get theoretical (...)

## Need some help Designing 16QAM Transmitter/Receiver(matlab)

I am trying to build 16qam Transmitter/Receiver in multipath fading channel, First I need to transmit Packet of 1500 bytes (12000 bits) through the channel and plot the ber. Then I need to transmit the same Packet of bytes + 20 additional bytes (12160 bits) and plot the ber. The problem is that I need to transmit both of the packets (...)

## Calculating BER in QAM

Hi, I'm trying to calculate ber in QAM modulation assuming AWGN and using an assumed SNR. I would like to plot ber against a varying SNR for 16qam 64QAM and 128QAM. Using a constant rate. An example of such a calculation would be most useful. Thanks Steve

## Alamouti with 16QAM modulation

I have simulated Alamouti schemes for BPSK and 16qam. The results for the Alamouti scheme wiht BPSK modulation are qute good but the one with 16qam modulation are really bad. I have compared the Alamouti scheme with 16qam modulation with simple SISO (16qam). THe performance of Alamouti is really bad (SNR vs (...)

## matlab code for 4QAM with SNR vs BER graph

Can ne one plz give me the matlab code for the simulation of 4QAM with SNR vs ber graph? Waiting.... cheers
