Demodulator

This file is about BPSK Demodulator. This file will generate the binary output as PSK modulated signal as an input. The input file should be *.mat file. In order to generate the output, you have to know your sampling frequency fs, carrier freaquency, fc and your bitrate.

This model is an 8-ary modulator/demodulator based on Pulse Amplitude Modulation (PAM).You can change the Eb/N0 parameter in the "AWGN Channel" block to see the effect of the channel noise on the demodulated signal while the simulation is running.The input is a sinusoid with a frequency of 1 Hz.

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise.The packet include:1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)2) Modulator (RRC filter)3) Demodulator (Matched Filter, RAKE receiver)4)...

LLR_DEMOD LLR Demodulator H = LLR_DEMOD_MEX(CONSTELLATION, MAPPING, METHOD) constructs a LLR demodulator object H for a given constellation, mapping and noise variance. The vectors CONSTELLATION and MAPPING are usually generated by using MATLAB Modem Modulation Modem. and contain the complex or...

From GUI we can generate random binary data, modulate them in frequency, add noise to the modulated signal and final demodulate received signal. Also it's possible to view some performance of the system.

This set of files implements a *compliant* ATSC demodulator and decoder that accepts a captured real-world RF ATSC signal as the input and produces an MPEG-II video transport stream as the final output. The models are built in stages demonstrating a top-down design flow leading from RF to the...

This application example implements an end-to-end baseband communications system compliant to the US MIL_STD_188_110B intended for long-haul and tactical communications.This model supports four different data rates: 1200bps, 600bps, 300bps and 150bps. It also implements two different interleaver...
