Method for detecting cable connection of intelligent antenna outdoor unit

Abstract

The present invention discloses a method for detecting the cable connecting of the outdoor unit of the intelligent antenna, which settles the problem that the connecting sequence can not be detected when the intelligent antenna array is connected with the front unit of the outdoor radio frequency by a radio frequency coaxial cable in the TD-SCDMA communication system. The invention presents a method for confirming the connecting sequence of the corresponding cable according to the estimated data of the communication channel, changing the complexor sequence in the antenna array direction, searching the maximum value of the energy in the air space, and the antennae array direction complexor sequence which corresponds with the maximum value. The present invention effectively settles the problem of detecting the connecting sequence of the of the radio frequency cable in the realizing of the intelligent antenna project; the detecting sequence of the present cable can be accurately detected while the upgoing communication channel is adopted to process the data according to the criterion that the space detecting receiving power is maximum traversing all the cables at the condition that the calculating difficulty is effectively controlled; the smooth arithmetic is adapted for the originality, the noise and disturbance are sieved and the correctness of the detecting arithmetic is increased.

Description

technical field [0001] The invention relates to a method for detecting the cable connection of an outdoor unit of an intelligent antenna in a wireless communication system, in particular to a method for detecting the connection of a cable adopted by an outdoor unit of an intelligent antenna in a synchronous Code Division Multiple Access (CDMA) communication system. Background technique [0002] Using the spatial characteristics of signal transmission and digital signal processing technology, smart antennas can realize the estimation of uplink angle of arrival (DOA) and downlink beamforming, so as to reduce interference, increase capacity, expand coverage, improve communication quality, and reduce emission. Power and the purpose of increasing the wireless data transmission rate. [0003] Under the condition of a certain user moving speed, for a synchronous CDMA communication system using time division duplex (TDD), the upper and lower channels meet the symmetrical requirement...

AI Technical Summary

Problems solved by technology

Since the smart antenna array generally adopts a multi-antenna system, during the construction process of connecting with the outdoor RF front-end unit, there are often cases where the connection sequence is wrong, which will greatly affect the performance and gain of the smart antenna system

Most of the existing solutions are limited to manual identification and detection, which is not only difficult to control in terms of accuracy, but also seriously affects the construction speed of base stations
