摘要
在WATM(无线异步转移模式 )网络中 ,无线链路与ATM(异步转移模式 )的光纤链路相比存在着误码率高、时延长和带宽有限等问题。针对RACH(随机接入信道 ) ,在介绍了DSA+ + 协议所采用的冲突分解算法的基础上 ,融入了SDMA(空分多址 )技术 ,得出了分析结果 ,表明RACH的吞吐量和时延性能都得到了很明显的改善。
In wireless ATM networks,there are such problems as higher BER,longer delay and limited bandwidth associated with the wireless link compared with the fiber link in ATM.Based on the collision resolution algorithm used in DSA ++ protocol,SDMA technique is introduced to the target random access channel (RACH).The analysis results show that the performance of throughput and delay in RACH has been improved substantially.
