This m-file finds the bit error rate performance of BPSK DS-SS system over (i) AWGN channel and (ii) Slow Rayleigh fading channel corrupted by AWGN. Compare the performance with simple BPSK system.
In this simulation I have used two functions.So to see the result open all the files and then run ber_performance file.
This m-file plots the transmitted signal of slow frequency hopped spread spectrum.This uses one symbol transmission per frequency hop.
This m-file finds the periodic ACF of all the m-sequences of length 31.In this program m-sequences of length 31 are generated and its periodic Autocorrelation function is plotted.
A uniform random number generator is used to generate the binary information sequence from the binary data source. The sequence of d-de?0d-deOaos and d-de?1d-deOaos is mapped into sequence of +E and d-deOCtE
where E represents the signal...
The script uses only one transmission symbol per frequency hop.
This m-file generate Gold Sequences of length 31 by taking the modulo-2 sum of two m-sequence generators.
This program generates filtered BPSK with proper pulse shaping filters such as ideal Nyquist, Raised cosine, Square root raised cosine and Gaussian filters. Determine the power spectrum of filtered BPSK signals.
Write a program to generate QPSK constant envelope signal waveforms(a)for given rectangular pulse shape. Select the carrier frequency as fc = 6/T.
(b)Repeat the experiment given that the signal shape is
g (t)= dldu(1-cos2dcdet/T) , 0...
This program generates BPSK signal waveforms and plot the power spectrum of unfiltered BPSK.
In this file there are two m-files.One is function and other is program. So during running the program save both file in same folder.First open the function rect ,then and run the ber_QAM file. You will get the required result.
