Abstract

The invention discloses an uplink receiving method based on dual-polarized antenna, which includes that a base station adopts a dual-polarized antenna composed of two groups of antennas to receive signals from a terminal, and corresponding base band signal is obtained according to the signal from the terminal; wherein, the signal and the base band signal all comprise training sequence part and data part; the base station performs channel impact response estimation towards the training sequence part of the base band signal to obtain channel impact response parameter; the base station generatescomposite system matrix and impact response matrixes corresponding to the two groups of antennas according to the obtained channel impact response parameter; the base station utilizes generated composite system matrix and impact response matrixes to perform combined detection processing on the data part of the base band signal to recover the data part information of the base band signal. Besides,the invention also discloses a downlink transmitting method based on dual-polarized antenna.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to an uplink receiving method based on a dual-polarized antenna and a downlink transmitting method based on a dual-polarized antenna for a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system. Background technique [0002] In the existing smart antenna technology, by using the spatial characteristics of signal transmission and digital signal processing technology, the uplink angle of arrival (DOA) estimation and downlink beamforming can be realized, so as to reduce noise interference and increase capacity , Expand coverage, improve communication quality, reduce transmission power and increase wireless data transmission rate. [0003] Since the array area of ​​the smart antenna is relatively large, it is a trend to use a dual-polarized antenna with a smaller antenna surface. In the patent application No. 200410084828.6 submitted on September 30, 20...
