✦ Synopsis

Understanding of indoor/outdoor multipath propagation structure is important in developing antifading techniques for high-speed digital radio access. That is clarified by measuring the direction of arrival (DOA), time of arrival (TOA), and relative power strength of incident waves. We propose a new algorithm to estimate these parameters in mobile communication environments. We have developed multipath propagation analysis equipment for applying the algorithm. The basic performances have been evaluated in an anechoic chamber. It became clear that it was possible to measure coupled TOA and DOA with high resolution and high accuracy within a short processing time in mobile communication environments.

## Abstract This paper presents simulation and measurement results of a six‐port direct conversion receiver for multipath propagation. Simulation results, using the Norton‐Bullington model of the multipath propagation and the receiver computer model, are presented and compared with bit‐error‐rate (
