function BW = bandwidth(DataRate,Overhead,FECR,BITpSym)
% This function caculates satellite operating band-width
% DataRate: Input data rate (Kb/s)
% Overhead: Link overhead factor (% Worst case)
% FECR: FEC rate coding
% BITpSym: Bits/Symbol

EffDataRate = DataRate*(1+Overhead/100);
EffTransRate = EffDataRate/FECR;
BW = EffTransRate*1.4/BITpSym;  % 1.4 is spectral expand due to spectral shaping
