Abstract
A radio receiver for improving transmission performance by applying prescribed processing to received signals having reached to plural antennas concurrently, and a despreader to be mounted in the radio receiver. In such a radio receiver, the received signals are decimation-sampled, and multiplexed into a multiple-signal, which is demultiplexed and prediction processed for interpolating the values decimated in the sampling. In the despreader, the transfer functions and despreading codes are multiplied in real time, and interpolation processing and despreading processing are performed based on the filtering characteristics set as the results of the multiplication. In a radio transmission system to which the present invention is applied, it becomes possible to perform all of desired synthetic processing, phase scanning, frequency scanning and feeding point scanning adaptive to an array antenna system, without lowering the performance of the system or increasing the scale and the price of the hardware.
