RADIO APPARATUS, METHOD FOR RECEIVING ITS SIGNAL, METHOD FOR MEASURING ITS FILTER COEFFICIENT, AND PROGRAM FOR MEASURING ITS FILTER COEFFICIENT

摘要

A radio apparatus is provided with analog RF circuits (1-4) by corresponding to antennas (A1-A4), and the circuits’ outputs are converted into digital signals by A/D convertors (5-8). The preceeding stage of adaptive processing that is its succeeding stage is provided with correction filters (12-15). Each correction filter has a filter coefficient for compensating for the difference between the characteristics of corresponding analog RF circuits and ideal circuit characteristics. This compensates for an error in characteristics between analog RF circuits. These actions are executed by DSP with software programs.
