Embodiment Construction

[0098] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings. According to these structural diagrams, those skilled in the art can easily realize the present invention.

[0099] figure 1 It is a structural diagram of a general RAKE receiving device. Two diversity antennas 101.1, 101.2 receive air signals, and convert them into baseband signals through corresponding two radio frequency channels 102.1, 102.2. The baseband signals are sent to the multipath search module 103 for multipath search. The search results are sent to the multipath allocation module 104 . The multipath allocation module 104 selects several multipaths with relatively high energy and the incoming signals from the corresponding radio frequency channel 102.1 or 102.2 and distributes them to each tracking, descrambling and despreading module 105.n, where n=1, 2, . . . , N. It is assumed here that the rake receiver has N branches. ...

Abstract

This invention discloses a send / receive and diversity method for an intelligent antenna and a device, in which, a dead zone process of an adaptive intelligent antenna is added to the receiving method. First of all, multiroute search and distribution on time domain to the baseband signals is carried out then to receive every distributed multiroute time delay with one intelligent antenna to process in signal beam weight and tracing de-disturb, de-expansion to renew the beam weight value, finally to carry out multiroute merge to get the data information.

Description

technical field [0001] The present invention relates to a code division multiple access communication system, more specifically to a smart antenna transceiver diversity method and device. The method and device of the present invention can be applied to a code division multiple access communication system using any array mode and any duplex mode. Background technique [0002] Code Division Multiple Access (CDMA) is a multiple access method, which is based on spread spectrum technology and has recently become an alternative to existing Frequency-Division Multiple Access (FDMA: Frequency-Divisoin Multiple-Access) -Division Multiple-Access) is another multiple access method applied to cellular wireless systems. Compared with existing methods, CDMA has many advantages, such as high spectrum utilization and simple planning. Because of this, the code division multiple access system has become the mainstream in the third generation mobile communication. [0003] At present, the sy...
