Abstract
Disclosed is a weight vector computing unit using a symbol-rate, a chip-rate and/or a mixed-rate in a Smart Antenna System. The weight vector computing unit is useful in a wireless communication network having a reverse pilot channel. Further, by using such the weight vector computing unit, high-speed broadband communications are available in a smart antenna system. In such 3-G wireless communications where both traffic signals and pilot signals are transmitted from a terminal, the weight vector computing unit calculates optimized weight vectors using the pilot signal and the calculated weight vectors are adapted to each traffic signal. The weight vector computing unit is configured to receive the received signal and/or the integrated signal in order to produce a weight vector for beamforming without any training signal.
