摘要

在ISM(工业、科学和医疗)设备辐射的电磁干扰下运行的无线通信系统，由于这种干扰的影响，其性能会急剧下降。为了设计一种在ISM干扰环境下有效、灵活地运行的直接序列扩频系统，本文介绍了一种采用自适应多码传输方案的直接序列扩频系统。在计算机仿真的基础上，研究了自适应多码DS-SS系统的误码率和吞吐量性能。仿真结果表明，采用自适应多码传输的DS-SS系统即使在ISM干扰环境下也能取得良好的性能。

A proposal of adaptive multicode transmission for DS-SS system under ISM interference environments

Wireless communication systems operating in the presence of the electromagnetic interference radiated from ISM (Industrial, Scientific, and Medical) apparatus are drastically degraded in performance by the effects of the interference. In this paper, to design a direct sequence-spread spectrum (DS-SS) system to be effective and flexible to operate under ISM interference environments, the DS-SS system which employs an adaptive multicode transmission scheme is introduced. Based on computer simulation, the bit error rate and the throughput performances of the adaptive multicode DS-SS system are studied. Simulation results illustrate that the DS-SS system with the adaptive multicode transmission achieves good performance even operating under ISM interference environments.
