The program distributes an amount power among ofdm subchannel to make the capacity of a channel.

Simple Matlab example simulating a BPSK transmission and reception in Rayleigh channel. The script performs the following(a) Generate random binary sequence of +1d-deOaos and -1d-deOaos.(b) Multiply the symbols with the channel and then add white Gaussian noise.(c) At the receiver, equalize...

Baseline Fit each column in "x".There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput.Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated...

This very simple m-function computes cross spectrum, coherence and phase at the same time. The input parameters are equivalent to pwelch.n or csd.m in MATLAB and use csd.m in the singal toolbox.It's very simple but useful for engineers.

function y = getiq(x,freq)this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spotORfunction y =...
