RADIO COMMUNICATION APPARATUS, RADIO TRANSMISSION METHOD, AND REPRODUCTION QUALITY EVALUATION METHOD

PROBLEM TO BE SOLVED: To easily perform the comparative evaluation of effects of multiple kinds of filter processing to be applicable to voice data before compression encoding by the acoustic feeling of reproduction voice.SOLUTION: A radio communication apparatus 1 includes a digital filter unit 11, a compression encoding unit 12, and a radio transmission unit 13. The digital filter unit 11 performs mutually different multiple kinds of filter processing with respect to one kind of voice data (VD1) and generates multiple kinds of processed voice data (e.g. FD1-FD3). The compression encoding unit 12 performs compression encoding with respect to the multiple kinds of processed voice data and generates multiple kinds of encoding data (e.g. ED1-ED3). The radio transmission unit 13 transmits the multiple kind of encoding data by radio, thereby to allow respective analog decoding voices, which are obtained by decoding the multiple kinds of encoding data, to be continuously reproduced in a receiver.
