Hi, I'm trying to calculate the theoretical ber for M-ary psk in the presence of a Rayleigh Channel. I've been using as a reference on how to do it but I haven't made much progress. In this example he says the ber for Bpsk is the integral of 0.5erfc(sqrt(y))p(y) from 0 to infi
How will u prove that ber for msb bit is less than ber for lsb bits in mqam....
hi can anybody sen me a program for psk modulation over frequencey selective channel........plzzzzzz thank u vey much in advance clear all; clc; %% M=2; % size of signal constellation k= log2(M); % bits per symbol n= 1000000;
Hi all, I have just completed my previous task on simulating a fading process with a first order butterworth filter. What I did was to run the following space-state equation for 10,000 time points and taking FFT of it. x(k+1)=x(k)exp^(-wT) + w(k), where w(k) is noise Next, I am tasked to find the ber for a Bpsk (...)
Hi, My work is to simulate the ber for siso,simo and mimo systems. So,if anybody have an idea ,please help me. Thanks
Hi everyone !!! I hope everybody is doing fine and great. I need the formula for SER(or ber) for 16 QAM in Rayleigh Channel. I will appreciate if someone can help!!!! thanks in advance, mesange
i need matlab code for Spectral Efficiency and ber for awgn, rayleigh and rician channels(fading models). also if any material then please provide it.
hi all can anyone please tell me how to calculate the theoritical ber for DBpsk... is it 1/2*erfc(sqrt(eb/n0))??? M very new to these concepts. so please help. thanks in advance
I try to implement the matlab code on ber for Qpsk in OFDM over rayleigh channel (with n taps). However the result is a straight line. There must be something wrong in my code but I cannot figure it out what is wrong. Could you please help me to check it. I have to hand the work soon. Please please please help. Thank you very much. clear;
hello , i need help for my matlab program for calculating ber for ofdm system..actually in my program i am got getting right curve for simulated result so plezz help me to knw where the problem is progam is written below ...... plezz help me to get this done.

I am trying to calculate the ber of OFDM system, lets say using simplest Bpsk modulation. I have experimental measurements of the channel impulse response, PDP with amplitudes and delay of the multipath components. I have formed OFDM symbols, modulated them and now it is time to pass them to channel. What is the most suitable way to simulate (...)

Hi everyone, Could someone give me a reference to compute the theoretical ber for an OFDM system using M-Qam modulation? I have tried to find it, but until now I just found the theoretical ber curve in a graph, but I would like to find the math expression. Best regards, Rodolfo
hi. i'm new in this. i have a noise generator module (frequency variation from 2kHz to 16 KHz )and psk module (bandwidth of 10KHz) . Now by using this i want to plot hte Eb/No Vs ber curve pls any one hlep me .
Dear all, I read many papers regarding on the ber test of SerDes link. Different papers use different PRBS sequence 2E7-1; 2E11-1; 2E15-1; 2E23-1 to test their ber. for a same link, different PRBS will result in different ber, e.g. 10E-12 or10E-7. Does anyone can help me understand which PRBS sequence should use in a (...)
Hi friends...i really need a simple transmitter and reciever circuits for psk and PCM..can anyone please share any circuits or ideas or links..thanks in advance!:D
to my knowledge, ber performance of MMSE is not characteristized yet. In general, the average ber calculation involves intergration over SNR, but SNR for MMSE is not readily available.

HELLO .. I want to test my transmitter for AWGN .. i have coded my transmitter and receiver using VERILOG hdl .... kindly if anybody has verilog code for AWGN .. where i can change SNR values .. and calculate ber for each SNR.....any suggestions for simulating AWGN and calculate ber.....
umm... there is no code only a graph. Here is what might have gone wrong. 1) less number of samples transmitted (monte carlo requires a good number for accuracy) 2) noise not generated properly Also, I don't find the graph to be funny
