Pull request overview

本 PR 完成《无线通信技术实验 02》中的信道编码（Hamming(7,4) + 选做卷积码/Viterbi）与信道均衡（ZF/LMS）核心函数实现，并补充实验报告内容，用于通过自动评分与生成结果图验证。

Changes:

  • 实现 Part 1：Hamming(7,4) 编码/伴随式/单比特纠错译码，并补全选做卷积码编码与 Viterbi 硬判决译码。
  • 实现 Part 2：ZF 均衡器最小二乘估计、FIR 卷积滤波、LMS 自适应均衡训练。
  • 新增 REPORT.md 实验报告内容，并修改 REPORT_TEMPLATE.md。

## 1. 实验目的

说明本实验希望掌握的信道编码、信道均衡和 GitHub 自动评分技能。
掌握 Hamming(7,4) 信道编码与单比特纠错的基本方法；理解多径信道导致的 ISI 以及 ZF/LMS 均衡器的设计与效果评估；熟悉使用 GitHub 自动评分与本地脚本进行实验结果验证。
