Explore MATLAB source code curated for "QPSK" with clean implementations, documentation, and examples.
Source code implementation for constellation diagram demodulation based on IEEE 802.11a standard, covering BPSK, QPSK, 16QAM, and 64QAM modulation schemes with digital signal processing algorithms.
This method compresses images using 2D-DCT, transmits them through QPSK modulation and AWGN channel coding, then reconstructs the original images via IDCT decompression - applicable to any image format with configurable compression and transmission parameters.
This file contains a highly practical QPSK bit error rate simulation implementation, featuring comprehensive channel modeling and performance analysis. Essential for digital communication system design and evaluation!
Comprehensive source code for QPSK modulation and demodulation covering the entire signal processing pipeline, including signal generation, constellation mapping, carrier modulation, and coherent detection algorithms.
Generate a random binary sequence exceeding 1000 bits and implement BPSK, QPSK, and 16QAM modulation schemes. Key outputs include: 1) Low-pass filtered waveform visualization (10 symbol periods); 2) Signal eye diagram analysis (5 symbol periods) with technical discussion; 3) In-band and out-of-band power spectral density plots using customizable low-pass filter parameters.
This code performs Bit Error Rate (BER) simulations for both BPSK and QPSK modulation schemes across various Signal-to-Noise Ratio (SNR) values. The simulation transmits at least 10^6 bits for statistical reliability and evaluates performance across 10 different SNR iterations to generate comprehensive BER curves.
This MATLAB model demonstrates a QPSK modulation system designed for transmission over a bandpass channel with center frequency fc = 100 Hz and bandwidth B = 30 Hz, incorporating AWGN at the receiver. The system employs SRRC filters with excess bandwidth α = 0.18, and implements an NDA timing recovery loop followed by a DD phase recovery loop in the receiver chain.
This document presents my implementation of MMSE calculation for QPSK MIMO channels with two-path fading. I urgently need assistance with a comprehensive article on channel estimation algorithms, specifically focusing on LS algorithm implementation for Rayleigh fading channels using MATLAB code, as my submission deadline is approaching rapidly.
This collection includes verified simulation programs for multipath fading, Rayleigh and Rice channel modeling, QPSK modulation, complete with test results and simulation diagrams. The implementations feature proper channel modeling techniques, BER performance analysis algorithms, and visualization functions for comprehensive communication system evaluation.
