摘要

提出了一种适合于分析扇形天线系统在室内信道中的性能的室内无线电传播确定性模型。利用该模型，对BPSK无线电调制解调器在不同大小的房间、不同功率水平的系统、不同停电要求和不同天线系统下的性能进行了评估。结果表明，如果全向天线在30m × 30m的房间内使用，数据速率不能达到5mbps以上，中断率为0.01，可接受错误率为0.0001。如果使用六扇区天线系统，以选择功率最大的扇区为选择标准，在相同的环境下可以达到2OMbps的数据速率。当数据速率为15mbps，发射机功率为低时，在10m × 10m的房间内，全向天线系统的中断概率不可能达到0.01。采用相同功率和数据速率的六扇形天线系统，在40m × 40m的房间内可提供0.01的中断率。

Performance Evaluation Of A Sector Antenna System In Indoor Radio Channels

A deterministic model for indoor radio propagation which is suitable for analyzing the performance of sector antenna systems in indoor radio channels is presented. Using this model, the performance of a BPSK radio modem operating in rooms with different sizes and the systems with different power level, outage requirements and antenna systems is evaluated. It is shown that if the omnidirectional antenna is used in a 30m by 30m room, the data rate cannot reach above 5 Mbps with an outage rate of .01 for the acceptable error rate of .0001. If a six-sector antenna system is used, and the selection criterion is to choose the sector with the largest power, a data rate of 2OMbps can be achieved in the same environment. For a given data rate of 15 Mbps and a transmitter power of lw, the omnidirectional antenna system cannot reach an outage probability of .01 with in a 10m by 10m room. The six-sector antenna system with the same power and data rate can provide the outage rate of .01 in a 40m by 40m room.
