This repo contains simulation code for DI-S-MMSE Turbo Equalizer and LMMSE Equalizer applied to OTFS Modulation.

High Performance Computing (HPC) and Signal Processing Framework

A set of Python class implementing basic several turbo-algorithms (e.g. : turbo-decoding)

Encoder and decoder for a parallel-concatenated convolutional code (PCCC)

Forward error correction algorithms optimized for embedded systems

本项目是信息论与编码课程的大作业，涵盖了卷积码 (Convolutional Codes) 与 Turbo 码 (Turbo Codes) 的核心算法实现。通过在 AWGN 信道下进行多维度仿真对比（不同码型、判决方式、迭代次数、码长等），系统分析了误码率 (BER) 性能。项目包含 Viterbi、BCJR 等经典译码算法，以及 Turbo 码的并行级联 (PCCC) 与串行级联 (SCCC) 架构，展示了交织增益、迭代收敛特性和误平层表现。仓库提供完整的源代码、仿真数据与绘图脚本，便于复现和扩展实验。

Convolutional coder and decoder in C

Design and simulation toolkit for Decomposed Parallel Concatenated Convolutional Codes (DPCCC): a novel turbo code structure with improved minimum Hamming distance. Includes decoder-free interleaver design, N-impulse design, and Monte Carlo BER/FER simulation.

Turbo-equalized rate-2 Multi-Stream Partial Response Signaling: a C++ BER and EXIT simulator on AFF3CT

Header-only library for error control coding (ECC) simulations and experiments. Can deal with arbitrary finite fields and complex field relationships, based on compile-time or runtime LUTs. Provides data structures and algorithms for matrices, vectors, and polynomials.
