Abstract

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
