Demodulation

The Files includ;The Filecy modulation and demodulation technique Platforms: Matlab

The demonstration of n-PSK modulation and demodulation with my own speech, with different value of n and sampling frequency and carrier, n = 2, 4, 8, 16 ,32... Platforms: Matlab

It can be used also for computing the BER (bit error ratio) for different Eb/N0 in an AWGN channel.MSK stands for Minimum Shift Keying. Requirements: - MATLAB 7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

You can rum these files by my_speech.m file, taking an value like my_speech(64, 'qam') in the command window of MATLAB. Platforms: Matlab

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. Platforms: Matlab

The Code describes the way to modulate or demodulate a signal shift in its phase. Platforms: Matlab

Basic familiarization about AM and FM, i have taken my speech to check whether AM or FM properly recover the signal or not, after modulation and demodulation. Platforms: Matlab

This Demo gives the user sufficient freedom to vary the values of modulating and carrier signal amplitude and frequency.Accordingly it displays the time domain waveforms of both the signals. i.e. modulating and carrier signal.It also provides means of evaluating AM Envelope and the corresponding...
