Matlab Signal Generator:
function [E1]=GPS_L1(Fs,BB_BW,CN0_IN,Tsig,FI,Doppler,Delay,numsat,flag_Datos,flag_local,flag_noise)
%[L1]=GPS_L1
%Fs= Sampling frequency [Hz]
%BB_BW= BaseBand bandwidth [Hz]
%CN0_IN= Carrier-to-noise-density ratio [dB]
%Tsig= Total signal time to generate [s]
%FI= Intermediate Frequency, 0 means baseband [Hz]
%Doppler = Doppler frequency [Hz]
%Delay = Code delay [s]
%numsat= Satellite Vehicle number(1-31)
%flag_datos = 1 -> Signal contains random telemetry bits 0 -> No telemetry
%flag_local = 1 -> Signal will be used as a local replica
%flag_noise = 1 -> Signal contains noise 0 -> signal is noise-free
