Abstract

<B>APARELHO E MéTODO PARA GERAçãO DE UMA PALAVRA SYNC E TRANSMISSãO E RECEPçãO DA PALAVRA SYNC EM UM SISTEMA DE COMUNICAçãO W-CDMA<D> é provido um método de sincronização de quadros sync recebidos com quadros sync de referência. Cada um dos quadros sync recebidos e dos quadros sync de referência tem uma palavra sync, e é dividido em um número predeterminado de frações, e cada fração é dividida em uma pluralidade de bits. No método, uma palavra sync de quadro é provida, para ter uma primeira correlação, quando os quadros sync de referência estiverem sincronizados com os quadros sync recebidos, e uma segunda correlação diferente da primeira correlação, quando a palavra sync recebida for uma versão deslocada da palavra sync de referência por um de dois números específicos de frações, por exemplo, tais como 5 ou 10.<B> APPARATUS AND METHOD FOR GENERATING A SYNC WORD AND SYNC WORD TRANSMISSION AND RECEPTION IN A W-CDMA COMMUNICATION SYSTEM <D> a method for synchronizing received sync frames with reference sync frames is provided. Each of the received sync frames and the reference sync frames has a sync word, and is divided into a predetermined number of fractions, and each fraction is divided into a plurality of bits. In the method, a frame sync word is provided, to have a first correlation, when the reference sync frames are synchronized with the received sync frames, and a second different correlation from the first correlation, when the received sync word is a displaced version of the reference sync word by one of two specific numbers of fractions, for example, such as 5 or 10.
