Hi! I need to simulate with matlab a qpsk and 8PSK modulations using LDPC coding. I need to obtain the theoricals graphs of the Eb/No and BER relationship for differents code rates and modulations (in fact, I need to obtain the graphs for Eb/No and BER relationship for a DVB-S2 system), but I can't find a BER formula for LDPC codes. Thanks!
Hi all, I have a file, I'll be channel coding it and the file name is Coded_file.txt. I need to modulate the file contents using qpsk,16QAM and 64QAM and then apply Rayleigh's fadding with path delay of in seconds and corresponding path gain of in dB. Inbuilt commands from matlab like qammod,qamdemod can be directly. P
Given 2 modulating message signals (I and Q): SI(t) = 0.5 sin(2pie 10t) + sin (2pie 20t ) SQ(t) = 0.7 sin (2pie 15 t) + 0.3 sin( 2pie 25t ) carrier frequency , fc = 500 Hz sampling frequency, fs = 63 kHz using qpsk Modulator What is the matlab coding for the simulation to obtain the plot of the amplitude spectrum of the modulated (...)

hi all, can some1 pliz avail me with matlab codes for Adaptive Modulation and coding(AMC), any digital modulations schemes(64QAM to qpsk) and turbo codes can do. thank u lots. legend1

Hi, If you are using matlab 2009a, you may find a complete Simulink model for IEEE? 802.16-2004 OFDM PHY Link, Including Space-Time Best wishes Ahmed
im a newbie for digital communication. currently i hav an assignment regarding on BPSK & qpsk matlab. that hav sthgs which im not understanding btw matlab coding and text book formula. as wat i read in text book, the BPSK transmitted signal is represented as S_bpsk(t)=m(t)*√(2Eb/Tb)*cos(ωc*t) but, in (...)
I am doing a matlab simulation on qpsk mod and demod passing thru AWGN channel. I am double encoding my signals to get better performance. The coding is RS(31,27) act as outer coding and rate 1/2 constrain length 7 polynomial (171,133) convolutional code act as inner coding. After doing all (...)
I am going to complete my PhD before X'mas in UK. And I am currently looking for a job. I have skills with C/C++, matlab, Fortran. And my research areas are as follow: Forward Error Correction (FEC), Error Control coding, Turbo Codes, Convolutional Codes, Coded Modulation Systems, Modulations (BPSK, qpsk, QAM), OFDM, MIMO, WiMAX, WiFi, DVB, (...)
Salam Alikom Okay here is a file that contains a design note on AGCs, and all of the matlab code to illustrate them. Have fun with them,
