直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。(DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.)

说明：  本文主要从自适应调制的算法及实现出发，引入了OFDM子载波分组的概念，详细阐述了五种固定阈值算法和子带BER预估计算法的原理及实现，并在此基础上加入自适应编码，实现自适应调制与编码。(Based on the algorithm and implementation of adaptive modulation, this paper introduces the concept of OFDM subcarrier grouping, elaborates the principle and implementation of five fixed threshold algorithms and subband BER estimation algorithm, and adds adaptive coding to realize adaptive modulation and coding.)
