<P>PROBLEM TO BE SOLVED: To achieve reception of high-quality information regardless of changes of a reception environment and low power consumption thereof. <P>SOLUTION: The radio receiver is provided with a plurality of antenna elements 101 for receiving radio signals, a means 111 which weights and synthesizes the radio signals received by a plurality of the antenna elements on the basis of a weighting factor stored in a weighting factor storage means 117, and a means 114 for demodulating the synthesized radio signals. The radio receiver comprises a means 115 which calculates transmission path responses of the synthesized radio signals, and detects the changes of the transmission path responses; and a means 116 which calculates the weighting factor when the changes of the transmission path responses are detected, and updates the weighting factor stored in the weighting factor storage means 117 by the detected changes of the transmission path responses and the calculated weighting factor. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
