| 摘 要： | 为了使各种终端易于移动、安装及避免室内复杂、昂贵的布线,近几年,随之也就出现了建筑物内(室内)无线通信的概念.本文就首次分析了在室内信道下分时片 ALOHA 协议的性能.分析结果表明:对分时片 ALOHA 协议,在平均信噪比为3CdB 时,信道吞吐量可高达0.61,远大于传统的0.368;在平均信噪比较低时(比如小于20dB),采用分集接收技术可以大大地提高信道吞吐量。

| Abstract: | Recently,with the rapid development of information and OA technology,more and more computer terminals are located in buildings.In order to provide mobility and easy-setup for the terminals and avoid complex,expensive wiring in buildings, the concept of wireless indoor Communications for indoor applications is appearing. In this paper,the performance of slotted ALOHA protocol in indoor environment is first analyzed,which shows that,the channel throughput of slotted ALOHA may be as high as 0.61 when average SNR is 30dB,far greater than the conventional 0.368;furthermore,by diversity techniques channel throughput may be dramatically improved,especially when average SNR is not high. |
