Radio apparatus, method for receiving its signal, method for measuring its filter coefficient, and program for measuring its filter coefficient

摘要

Corresponding to antennas analog RF circuits are provided and their outputs are converted by A/D converters to digital signals. Subsequent thereto and preceding an adaptive array processing, correction filters are arranged. Each correction filter has a filter coefficient for compensating for a difference between a characteristic of an analog RF circuit corresponding thereto and an ideal circuit characteristic. Thus an error of a characteristic between the analog RF circuits can be compensated for. The series of operations are implemented by software.
