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。该模型考虑了直接的视线路径和通过墙壁反射到达的路径，以确定发射器和接收器之间的所有现有路径。利用该模型，比较了双相移键控(BPSK)和BPSK/DFE(决策反馈均衡器)无线电调制解调器全向和六扇形天线在同一房间工作时的中断概率。分析了房间大小、数据速率、传输功率和扇形天线模式对系统性能的影响。

Comparative performance evaluation of sector antenna and DFE systems in indoor radio channels

A deterministic model for indoor radio propagation that is suitable for analyzing the performances of sector antenna systems in indoor radio channels is presented. This model considers the direct line of sight path and the paths arrived through reflections from the walls to determine all the existing paths between the transmitter and receiver. Using this model, the outage probabilities of binary phase shift keying (BPSK) and BPSK/DFE (decision feedback equalizer) radio modems with omnidirectional and six-sector antennas operating in the same room are compared. The effects of room size, data rate, transmitted power, and sector antenna patterns on the performances of the systems are analyzed.<>
