摘要

首先，从线性码和压缩感知码两个方面对现有无源多址的编码方案进行了介绍，分析比较了无源多址扩频方案中Pradhan和Ahmadi提出的两种扩频序列探测器的性能；然后，对于Amalladinne在2020年提出的压缩感知编码方案进行了功率的重新分配；最后，仿真结果显示，在活跃用户数较低时，改进后的方法有一定的性能提升。

Abstract

Firstly

the existing unsourced multiple access coding schemes were introduced in two aspects: linear codes and compressed sensing codes. On this basis

two unsourced multiple access spread spectrum sequence detector schemes proposed by Pradhan and Ahmadi were analyzed and compared. Then

power was redistributed for the compressed sensing coding scheme proposed by Amalladinne in 2020. The simulation results showed that when the number of active users is low

a certain performance improvement is observed.
