Embodiment Construction

[0045] In order to solve the disadvantages of the traditional technical solution, the present invention further elaborates the device and method for selecting and processing the super path in a WCDMA system according to the present invention through the following specific examples. Limitations of Invention.

[0046] The technical scheme of the method for super-path selection processing in a kind of WCDMA system described in the embodiment of the present invention is as follows:

[0047] Shown in conjunction with accompanying drawing 2, a kind of method for processing super-strong path in WCDMA system, it comprises the following steps:

[0048] Step 201, using the searcher to calculate the ADP value of phase points corresponding to the window width of the task;

[0049] Step 202, use the super-path selection algorithm to find whether there is a super-path, if there is a super-path, use a special filter coefficient to filter the super-path, put the filtered result into the cand...

Abstract

The invention discloses a device of superstrong path choosing process in WCDMA system, it can be used in process of superstrong path which is in ADP value of mission window wide phase point in multi path management of WCDMA system, it includes: the ADP value of mission window wide phase point can be calculated by searcher; whether is there superstrong path can be checked by the superstrong path choosing arithmetic, if there is superstrong path, the superstrong path is filtered by special filter coefficient, the result which is filtered is placed to the candidate path result, other ADP value is placed into the candidate path result for later process. The invention realizes the stability which can guarantee the multi path search, decreases the void alarm, at the same time the hardware is easy to realize, the consumption of hardware is few, the work efficiency is quick.

Description

technical field [0001] The present invention relates to the third-generation mobile communication system, in particular to a super-strong path selection processing method and device in multi-path management of wideband code division multiple access system (WCDMA). Background technique [0002] In the WCDMA (Wideband Code Division Multiple Access) system, in order to combat multipath fading, the RAKE receiver is used to process the received signal, and for the RAKE receiver, if the channel estimation results are simply assigned to the RAKE receiver Taps, some taps may be assigned pure noise estimates, so multipath search technology is usually used to identify channels for channel estimation results, reduce the possibility of such allocation errors, and improve the performance of the RAKE receiver. The multipath search function includes estimation of energy delay characteristics and multipath allocation. Due to the influence of thermal noise and interference, the estimation of...
