Please post matlab code for ber of ofdm with qpsk its urgent thank you in advance
I have built an ofdm transceiver with rayleigh channel using standard PDP's Like EPA,EVA and ETU.The problem is I am getting very high BER even for BPSK i.e 50-60 % or higher bits in error.Scatterplotting confirms ofdm transceiver blocks include: ---- Random Data -- Modulation(BPSK,qpsk,QAM) -- Serial2Parallel -- IFFT -- CyclicPrefix >>>
I need matlab code for reduction of ici in ofdm with qpsk and qam monulation scheme.please help me
Hi all, I'm in dire need of the matlab code for BER of ofdm with MRC receiver over rayleigh fading channel for different modulation scheme such as BPSK, qpsk, M-QAM. If u have those, plz send to me: Thank u in advance.
Hello, Looking for how to modelize with matlab ofdm with qpsk in a Gaussian channel. THANK YOU VERY MUCH
I used an matlab example " syncCarrierFreqMSKSignalRecovery" to construct my model and apply it for qpsk system,it works . but when i applied it to ofdm-qpsk , it doesn't work. Kindly advice matlab Code ============ %Initilization %%%%%%%%%%%%%%%%%%%% nBitPerSym = 64; % number of bits per (...)

Can anyone give me turbo coded ofdm code? modulation(qpsk/8PSK/16PSK), turbo encoder, ifft, channel, fft, turbo decoder(log map), demodulation with 256 subcarriers. Thanks in advance....
Hello to everyone, i need help to finish the last two comments in my matlab code.Thanks in advance for your time and assistance guys!!! clc; N = 1024; %FFT points M = 2; %qpsk efficiency CP = 1/16; %CP length PCKS = 1; %Number of packets for pak = 1:PCKS Bit_Block = randint(1,N*M); X = 1/(sqrt(2)) * ((2*Bit_Block(1
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;
i m not completely familiar wid matlab therefore i m faceing the problem while getting BER curve for ofdm using qpsk modulation channel used is AWGN......... plz plzzz help me out wat i m doing wrong ........... i hv to submitt that assignment .......thx in advance clc; clear all rand('seed',0); randn('seed',0); packets =100; (...)
I Need matlab code for Performance analysis of Multi- tone CDMA using ofdm-qpsk......plz anyone help for me..................
Have you looked at bertool in matlab?
hey all!! Right now i m doing my final project and it s the first time that i use matlab and SIMULINK , I would like to know if i can do ofdm model in simulink and then do kiend of program using the GUI to change the kind of the modulation i mean with PSQK or QAM 16 i m wondering the posibility to do that , i appreciat your Help!!!
to add zeros, you have to add them as shown in this link: it is message number 52 note that the output zero is at the center i mean the zero frequency is at the center. check out it, it is very useful.
Hello Everyone, I have written this matlab code for a simple convolutionally coded ofdm system with qpsk and over a rayleigh fading channel. The problem I have however is I do not get the desired BER plot for the code. Can someone please tell me where I have gone wrong in this code? Thank you
I am trying to implement Cofdm using Reed Solomon(255,239).The hindrance i face is that i use qpsk modulation,after reed solomon perform qpsk modulation i need my bits in the range of 0:3.But by performing reed SOLOmon encoding from 240th bit bit position to 255th bit position i have my bits in the range of 0:255.hence i can't use inbui
Hi, can I get a matlab simulation code for ofdm implementing qpsk MODULATION.. ITS URGENT PLZ,,,,
Can anybody tell me some nice tutorials for doing some GFSK,qpsk,ofdm modulation using matlab simulink? Thank You Soma
i am writing code for equalizers in matlab ..can anyone help me
Dear All Can you send me a syntax command for qpsk mod. using matlab witah M=2. in order to calculate the BER for ofdm. thanks
