MATLAB Imitation Modeling for the BER of the Satellite Communication System using QPSK and OFDM Modulation with LS Channel Estimation based on Pilot Signals in the Transionospheric Communication Channel with Rician Fading, Multipath, Frequency Selectivity and Limited Coherence Bandwidth

Contains codes various Digital Modulation Schemes (like AM, DSB-SC, SSB-SC FM, BPSK, QPSK, 16-QAM, DBPSK, DQPSK) in MatLab from scratch ie. without built-in MatLab functions

This is Matlab implementation of modulation and demodulation of QPSK signals with added white Gaussian noise

Investigating the performance of an OFDM-based communication system with QPSK and QAM modulation and effects of AWGN and multi-path channels.

Simple model of BPSK, QPSK & 8QAM Modulator and Demodulator in MATLAB.

Estimation and correction of IQ imbalance in a QPSK modulation

Quadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees). QPSK allows the signal to carry twice as much information as ordinary PSK using the same bandwidth.

Contains ( QPSK, 16 QAM, DBPSK, DQPSK) modulation schemes from scratch in MATLAB.

Practical work on a QPSK comunication with differential code

A QPSK system with symbol duration Ts = 2 ns and carrier frequency fc = 1 GHz was implemented, and response was analysed with different transfer functions in the presense of additive white gaussian noise

The simulation project focuses on various common problem in a baseband equivalent QPSK system.
