Dear all, I have a problem in understanding LMMSE channel estimation in comb-pilot type of OFDM. I get stuck to find the auto covariance matrix of the pilot...
Hi, I have created a QPSK modulator for passband in matlab; created baseband BPSK and then upconverted. Code: Fs = 10000; fc = 1000; n = 0:1/Fs:1; M = 4; ...
To do demodulation for this type of modulation you need to multiply each filtered signal with its corresponding carrier such as the cos by the cos and the sin...
Hi, Anyone can please tell me how can I do a simulation for channel capacity using any modulation scheme for awgn and rayleigh channel. I mean a simulation ,...
yeah I agree, but what then, I should use a low pass filter? Would it convert it into baseband? How to generate a signal of 200 KHz BW at 1MHz? Would I have to...
Hi all, Please i need this journal paper titled Punctured super orthogonal space time trellis code by Yun Zhu and Jafarkhani, H. It appeared in IEEE...

Hi all, I started to doin my research to implemented OFDM to FPGA. Can anyone help me,where to start??? and can anyone help me with some design 802.16 in...
Start by learning how to "design" an OFDM modem according to requirements. Then move on to WiMAX. It would help you a lot. ________________________________ ...
Hello everyone, I am working on OFDM and I need codings and some materials for the PARP reduction in the OFDM system.If somebody can help me in this...
Hello everyone, I have a confussion about the delay spread of a multipath channel and the symbol rate of an OFDM transmission. I am working on a simulation of...
Hello friends; i'm working on pilot based channel OFDM estimation,i want to collaborate with people who works in this topic.please is there someone interested....
Hi i am currently working in linear precoding in ofdm :combination between ofdm and cdma and i like to collaborate with people working in this topic ...
Hi, As you know in OFDM channel estimation there's 2 ways to estimate the channel, pilot methods and blind methods,whitch one do you use in your study with...
I'm working in the same topic,do you have any idea how to fulfill the shanon sampling theorem in OFDM symbol with pilots.I have some papers about it if you're...
hello friends can any one of u tell me how to simulate a time variant channel in an ofdm system. i am assuming that the channel has 'L' discrete time taps. I...
Hi all.Please help me I am looking for the code of Wavelet OFDM. I need it for my project before graduating from university. Help me. Thanks so much....
