%This function pass the Input Signal through the Channel

%Input Parameters:-
%SignalIn: Input Signal which will be passed through the channel

%Output Parameters:-
%SignalOut = Output Signal after being passed through the channel.

function SignalOut = Channel(SignalIn)
%Channel Bandwidth = 1 MHz
ChannelBandWidth = 1 * 10 ^ 5;
N_0 = 10 ^ -6;
NoisePower = N_0/2 * (2*ChannelBandWidth);
AWGN = randn(1, length(SignalIn)) * (NoisePower .^ 0.5);
SignalOut = SignalIn + AWGN;
%SignalOut = SignalIn;
