Qpsk

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication. Platforms: Matlab

In this project work I try to design a QPSK modulator with SIMULINK/ Matlab. Generate PN-code as data and mapping for I & Q fitted to Embedded (M. file) Odd/ Even, for processing and sum them to produce QPSK signal Platforms: Matlab

OFDM Signal generation and decoding using QPSK as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. QAM4 and QPSK is same modulation technique. Just run the Model and with different SNRs in the Channel Block observe the... Platforms: Matlab

This program performs a Monte Carlo simulation of a coherent QPSK communication system and plot the error probability performance over additive whit Gaussian noise channel. The detection is based on correlation metric. Simulation is performed for 10,000 bits and measurements are made accordingly. Platforms: Matlab

This program calculates BER curve against SNR for QPSK Modulation in Gaussian Environment.It calculates 100 errors for for each SNR value before calculating BER. This gives a good approximation of BER.I hope this will help students alot.Please feel free to contact me should anyone has any queries. Platforms: Matlab

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 isg (t)= dldu(1-cos2dcdet/T) , 0 d-OC-TA t d-OC-TAT 0 , otherwise Platforms: Matlab

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel). Platforms: Matlab

This program is a script file, which computes the bit error rate of QPSK scheme over Rayleigh fading channel and shows in comparison with its performance over AWGN channel. Platforms: Matlab
