METHOD AND DEVICE FOR DETECTING PRIMARY SYNCHRONIZATION SIGNAL AND GENERATING SEQUENCE IN LONG TERM EVOLUTION (LTE) SYSTEM

摘要

Disclosed are a method and device for detecting a primary synchronization signal and generating a sequence in a LTE system, to solve the problem that the overhead for storing the local primary synchronization sequence is too much during the initial cell search procedure in 3GPP LTE system. The method for detecting the primary synchronization signal includes: directly generating the local primary synchronization signal sequence with equal amplitude in the time domain as a matched filter; performing front-end processing for the received signals; performing matched filtering between the received signals after front-end processing and the local primary synchronization signal sequences; determining the outputted amplitude of the signal sequence obtained after the matched filtering; and then obtaining the detection result of the primary synchronization signal sequence.
