Embodiment Construction

[0057] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, a detailed description of well-known functions and configurations incorporated herein is omitted for brevity.

[0058] However, before giving a description of the invention, consider a model of a received signal received at a receiver of a base station (BS). It is assumed that the receiver of the base station comprises a receive antenna array with a plurality of receive antennas (Rx ANT). Considering its cost and size, the receiving antenna array is generally installed only on the receiver of the base station, but not in the receiver of the mobile station (MS). That is, it is assumed that the receiver of the mobile station includes only one receiving antenna.

[0059] Additionally, although the present invention can be used in all systems utilizing Frequency Division Multiple Access (FDMA), Time Division Multiple Acc...

Abstract

A base station having at least one reception antenna generates a reception beam using a previous reception beam weight and a despread signal of a current reception signal, calculates an error value indicating a difference between the current reception signal and a desired reception signal, and calculates a current reception beam weight using the previous reception beam weight, the despread signal and the error value. The base station generates a reception beam weight step value using the error value and an output signal, calculates a difference between the previous reception beam weight and a product of the reception beam weight step value, the despread signal, and a conjugate value of the error value, as the current reception beam weight, and selects the reception beam weight step value such that the current reception beam weight becomes the optimal reception beam.

Description

technical field [0001] Generally, the present invention relates to a device and method for receiving data in a mobile communication system using Adaptive Antenna Array (AAA) technology. ) device and method for receiving a signal using a receiving beam weight generation scheme. Background technique [0002] The next generation mobile communication system has evolved into a packet service communication system that transmits burst packet data to a plurality of mobile stations (MS). The packet service communication system is designed to send massive amounts of data. For high-speed packet services, such packet service communication systems have been being developed. In this regard, the 3rd Generation Partnership Project (3GPP) (a standardization organization for asynchronous communication technologies) proposes High Speed ​​Downlink Packet Access (HSDPA) to provide high-speed packet services, while the 3rd Generation Partnership Project 2 (3GPP2) (synchronous The Standardizati...
