disper.m

it is a simulation about ML synchronization algorithm in OFDM systems,you can slao see a function pi

function [sigma2, sigma]=disper(indata)
%DISPER Summary of this function goes here
% calculate dispersion and standard deviation
%   Detailed explanation goes here
%*********************** variables **********************
% indata : Input data
% sigma2 : dispersion
% signa : standard deviation
%********************************************************
% calculate average value
mvalue= sum(indata)/length(indata);
% calculate square average
sqmean= sum(indata.^2)/length(indata);
% calculate dispersion
sigma2=sqmean-mvalue^2;
% calculate standard deviation
sigma=sqrt(sigma2);
