Lifetime Cable Channel

The comb pilot aided channel estimation in ofdm modulation is considered. The power of pilot subchannels is under the control.The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication.

The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.The discrete input is...

I'm actually having trouble with the equalization of the channel, because the doppler effect introduces phase rotation, which I don't know how to correct. If anyone could help me, I' d be really thankful.

Here is a simulation based proof highlighting the superiority of the MMSE[Min Mean Sq Error] channel estimator over the LS[Least Sq] estimator.The two parameters of evaluation turn out to be, quite logically, the SER[Symbol Error Rate] and the Mean Square Error.The channel is assumed to be...

VAC is intended to connect several audio applications together in real time. It's like a sound card with hardwired input and output: when an application sends an audio stream to a virtual cable, other applications can record this stream from the other cable end. Thus, you can record and process...
