Abstract: In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited ...

Satellite Uplink and Downlink Simulation is a communication system model developed using MATLAB Simulink. This project simulates the uplink (ground to satellite) and downlink (satellite to ground) ...

The modulators are the basic requirement of the communication systems they are designed to reduce the channel distortion & to use in RF communication hence many type of carrier modulation techniques ...

Abstract: Transmitting high capacity under low SNR conditions is increasingly a challenge in many wireless and free-space communications applications. E.g. in free space optical satellite links ...

This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors ...
