Abstract

DISPOSITIVO DE ESTAçãO BASE EM TRANSMISSãO COM MúLTIPLOS TRANSPORTADORES, DISPOSITIVO DE ESTAçãO MóVEL, E MéTODO DE BUSCA DE CéLULA. A presente invenção refere-se a um dispositivo de estação móvel capaz de reduzir o processamento de busca de célula. Nesse dispositivo,uma unidade de detecção de temporização FFT (603) detecta uma temporização de símbolo e uma unidade de detecção de temporização de quadro (606) detecta uma temporização de quadro pela utilização do símbolo de detecção de temporização de quadro. Depois de uma temporização de quadro ter sido detectada, uma unidade de detecção de grupo de código (608) detecta um grupo de código e uma unidade de identificação de código de criptografia (610) identifica um código de criptografia. Isto é, o processo de detecção de temporização de quadro é separado do processo de detecção de grupo de código e depois da detecção da temporização de quadro, uma temporização de símbolo multiplicada pela seqüência de grupo de código é identificada de forma que o grupo de código seja detectado apenas na temporização de símbolo.
