Explore MATLAB source code curated for "误码性能" with clean implementations, documentation, and examples.
Documentation and independently developed simulation programs for two cooperative communication schemes (AF and DF), enabling comprehensive comparison of their bit error rate performance under various channel conditions.
A simulation program for precoding based on channel quantization feedback, implementing uniform quantization and LDL decomposition-based precoding techniques to evaluate system bit error rate performance under different feedback bit conditions (1-bit, 2-bit, 3-bit).
Implementation of QPSK modulation and demodulation under Gaussian white noise and Rayleigh fading channel conditions (excluding multipath interference), using quasi-analytical methods for bit error rate performance calculation. The simulation workflow covers signal generation, filter configuration, QPSK modulation, additive white Gaussian noise injection, Rayleigh channel fading, QPSK demodulation, and BER computation with algorithm-specific implementation details.
QPSK modulation implementation; Comparative analysis of BER performance between DQPSK and QPSK over AWGN channels; OFDM system architecture and implementation
Simulation of bit error performance for a (2,1,2) convolutional code encoder-decoder in a Binary Symmetric Channel (BSC), plotting the corrected bit error rate versus channel bit error rate curve, with encoder generator polynomials g1=[111] and g2=[101]. The implementation involves convolutional encoding using polynomial generators, BSC channel modeling with crossover probability, and Viterbi decoding algorithm for error correction.
