Radio measurement method and radio measurement apparatus using multi-antenna channel multiplex

摘要

A radio measurement apparatus comprising: an array antennal selection unit selecting array antennas corresponding to received signals; a reference path selection unit selecting a reference array antenna; a signal processing unit selecting a reference antenna channel through analysis of signal characteristics measured through two reception channels; a sequential channel multiplex unit determining sequentially inputting received signals of remaining array antennas to output the sequentially input signals to a receiver; and a correction signal input unit compensating amplitude and phase characteristics of the respective reception channels.

1. A radio measurement apparatus comprising:
an array antenna selector selecting array antennas corresponding to received signals among multi-band array antennas; a reference path selector selecting a reference target antenna for preferentially performing an antenna reception operation with respect to a reference target channel among the selected array antennas; a signal processor selecting a reference antenna channel through analysis of signal characteristics measured through two reception channels for two reference target antenna paths; a sequential channel multiplexer determining the selected reference antenna channel as a first reception channel and sequentially inputting received signals of remaining array antennas to output the sequentially input signals to a receiver; and a correction signal inputter compensating amplitude and phase characteristics of the respective reception channels after the array antennas are selected, wherein the reference path selector selects two reference target antennas having no influence of radio wave shadow in possible signal arrival directions with respect to an antenna array, and wherein the two reference target antennas are located such that each of the two reference target antennas provides a non-overlapping 180° signal reception.
