ADAPTIVE RECEIVING DEVICE FOR ANTENNAS

摘要

The adaptive receiving block 2k for the k-user generates a receiving signal by the k-th user the m-th pass inherent antenna directivity pattern respectively, obtains the k-th user demodulation signal by demodulating and adding for each pass simultaneously and outputs weight control error signal e' kl~e'km for the purpose of forming directivity pattern for each pass. The weight control error synthesis circuit 3 optionally synthesizes weight control error signal e'kl~e'kM and outputs synthesis weight control error signal e kl~e kM. Synthesizing weight control error signals with respect to passes whose arrival directions of multi-pass of each user are close, performing a control without synthesizing weight control errors with respect to passes whose arrival directions are apart, increasing the information available for adaptive control and enhancing an adaptive control characteristic and an interference suppression ability.
