Direct Sequence Spread Spectrum (DSSS) for BPSK, QPSK and 16QAM modulations

BPSK, QPSK and 16QAM DSSS Tx and Rx with multipath channel

You are now following this Submission

There are 3 functions containing the BPSK, QPSK and 16QAM transmitter, channel (multipath Rayleigh and exponentially decaying plus AWGN) and a script which calls the 3 functions and plots BER and PER results. For more information, please, have a look to this post: https://sites.google.com/site/solutionsbehindthesciences/towards-5g/bpskqpskand16qamdssstxandrxwithmultipathchannel
Also feel free to comment or ask :) Thanks!
