Title: Adaptive antenna receiver
Inventor: YOSHIDA NAOMASA
IPC: H04B1/707
Filed: 2001-06-06
Abstract: PROBLEM TO BE SOLVED: To provide an adaptive antenna receiver that can significantly reduce the arithmetic amount, so as to realize superior path detection characteristics and superior reception demodulation characteristics. SOLUTION: A multi-beam former 1 receives a multi-beam of a spread signal by each antenna and outputs a spread signal by each beam. A correlator 31-1 for path reception means 3-1 to 3-L applies inverse spread processing to the spread signal by each beam selected in each path timing, and a weighting synthesis means 32-1 uses a weight specific to a user, that is adaptively generated to apply weighted synthesis to the outputs of the correlator 31-1, to receive the signal. A RAKE synthesis weighting means 33-1 applies weighting to an adaptive weighting synthesis output to correct phase fluctuations and conducts weighting, to maximize an SINR(signal-to-interference noise ratio), after path synthesis. A synthesizer 4 sums the outputs of RAKE synthesis weighting means 33-1, to conduct path synthesis and provide an output of a demodulation result with high quality.
