Real-time antenna data searching method, device and site

Abstract

The execution mode of the invention provides a real-time antenna data searching method, comprising the operation of carrying out dedicated physical control channel (DPCCH) search and enhanced physicalcontrol channel (E-DPCCH) search on the real-time antenna data; the invention is characterized in that the method also comprises the operation of carrying out E-DPCCH non-relative search on the received data transmitted by the real-time antenna to obtain multi-path information; carrying out multi path separation on the multi-path information to obtain a multi-path separation result; generating atough judgment result according to the multi-path separation result;; demodulating the tough judgment result and the multi path separation result to obtain a demodulating result; and configuring the searching mode of the next time interval according to the demodulating result. The invention also provides a real time antenna data searching method and a site. With the technical proposal adopted, deadlock can be reduced and Boosting search is supported.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and site for real-time antenna data search. Background technique [0002] With the development of communication technology, users have higher and higher requirements for service speed, and high-speed services occupy an increasingly important position in communication. In order to switch between high-speed and low-speed services, the algorithm of the inner ring and outer ring does not Adjustment, the R7 version of Wideband CDMA (WCDMA) introduces Enhanced Dedicated Physical Control Channel (E-DPCCH) Power Boosting to search real-time antenna data, and then supports Boosting search. [0003] The specific implementation scheme in the prior art is as figure 1 As shown, it includes: the DPCCH search unit receives the data of the real-time antenna and searches to obtain multipath information, and at the same time, the coherent search unit of E-DPCCH receives the data...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found the following problems in the prior art: Since the coherent search unit of the E-DPCCH in the technical solution provided by the prior art performs coherent search based on the hard decision symbol and Boosting, when it is In any of the following two cases, no hard judgment result (also called hard judgment symbol) will be generated, so the coherent search unit of the E-DPCCH cannot perform coherent search, thus falling into a deadlock state, and cannot Support Boosting search

[0005] 1) Neither the E-DPCCH coherent search unit nor the DPCCH search unit can search for path information in a certain slot

[0006] 2) Boosting exists immediately after the channel is established, and the DPCCH search unit cannot search for path information
