ADAPTIVE SIGNAL PROCESSOR AND METHOD THEREFOR, ADAPTIVE ARRAY ANTENNA SYSTEM, RADIO DEVICE, AND WEIGHTING FACTOR CALCULATING METHOD

摘要

PROBLEM TO BE SOLVED: To improve communication quality by constantly and continuously executing adaptive signal processing for calculating weight (a weighting factor) when a training signal to be referred becomes burst reception. SOLUTION: The adaptive signal processor is provided with a training signal storage 5 which stores the training signal included in a received signal received by an array antenna, a training signal supplier 6 which supplies the received training signal to an adaptive signal processing part 3 during a period when the training signal is included in the received signal and partially repeatedly supplies the training signal in the training signal storage 5 to the adaptive signal processor 3 during a period when the training signal is not included in the received signal, and a reference signal generator 7 for supplying the corresponding known reference signal to the adaptive signal processor 3 in accordance with the supply of the training signal.
