Adaptive receiving device removing interference from users and multi-paths by antenna directivity control

Abstract

The adaptive receiving block 2k for the k-user generates a receiving signal by the k-th user the m-th path inherent antenna directivity pattern respectively, obtains the k-th user demodulation signal by demodulating and adding for each path simultaneously and outputs weight control error signal e′kl˜e′kM for the purpose of forming directivity pattern for each path. 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 paths whose arrival directions of multi-path of each user are close, performing a control without synthesizing weight control errors with respect to paths whose arrival directions are apart, increasing the information available for adaptive control and enhancing an adaptive control characteristic and an interference suppression ability.
