Problems solved by technology

[0024] Other disadvantages of this approach include that, due to the presence of strong interference from other users (high rate users, i.e., users with a high transmission rate), the desired signal turns out to be canceled by the interference and it is impossible to be certain about the arrival of the desired signal Correct solution for direction and angle range

Embodiment Construction

[0066] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, a detailed description of well-known functions and structures incorporated herein will be omitted if they are not necessary to explain the subject matter of the present invention.

[0067] In the first embodiment of the present invention, the first method of forming the antenna pattern of the BS adaptive antenna array will be firstly introduced below, wherein the common pilot signal is transmitted by one of the antenna elements and the information signal is transmitted by all antennas Array elements are transmitted to each user.

[0068] For each user, the search for the user's signal is performed by determining the temporal position of the path signal. Pick the signal whose power is at its maximum. Next, a sequence of estimates for the angle of arrival of the signal is determined.

[0069] To generate each signal...

Abstract

A directional diagram forming method and a device for a self-adaptive antenna array in a base station are provided. The method comprises steps: generating complex correlation responses to a signal received by the antenna array in association with L different directions, respectively; calculating discrete values of an antenna pattern in a reverse channel in association with the L different directions, respectively; combining the generated complex correlation responses with the discrete values of the antenna pattern associated therewith; and generating weight vectors of the antenna array in a forward channel.

Description

[0001] This application claims the title "Method and device for forming a pattern of an adaptive antenna array in a base station", filed at the Russian Intellectual Property Office and assigned serial number No. 2002103215 as priority, the content of which is hereby adopted merged together for reference. technical field [0002] The present invention generally relates to radio engineering, and more particularly, relates to the method for receiving and transmitting radio signals using an adaptive antenna array in a CDMA (Code Division Multiple Access, Code Division Multiple Access) cellular communication system. Moreover, the present invention can Applied to a BTS (Base TransceiverStation, base station radio transceiver station) receiving device, the device forms an antenna pattern for each mobile user on the reverse and forward channels. Background technique [0003] The application of adaptive antenna array in CDMA BTS significantly improves the communication quality and sy...
