This MATLAB program simulates a wireless communication channel, incorporating different modulation schemes (BPSK and QPSK), the effects of noise, interference, and ...
This project focuses on the design, simulation, and performance optimization of two key digital modulation techniques — Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying ...
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 ...
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 ...
ABSTRACT: The manuscript developed an optimal frequency band transmission system structure of QPSK. The software programming experiment of this complete QPSK optimal band transmission system is ...
Four-dimensional QPSK modulation transmission scheme based on entropy-coding-aided symbol selection.
We propose a four-dimensional quadrature phase shift keying (4D-SS-QPSK) modulation transmission scheme based on entropy-coding-aided symbol selection. The proposed scheme integrates Huffman coding ...
