Abstract

MÉTODO E APARELHO PARA UM CANAL DE SINCRONIZAÇAO EM UM SISTEMA OFDMA. Um método e aparelho são providos para transmitir um sinal de acesso múltiplo de domínio de freqúência ortogonal (OFDMA) incluindo um sinal de canal de sincronização transmitido dentro de uma porção localizada de uma largura de banda do sinal OFDMA (818), o sinal de canal de sincronização tendo simetria de domínio de tempo predeterminada dentro da porção localizada da largura de banda (816). O sinal de canal de sincronização habilita um método de pesquisa de célula e aquisição inicial com baixa carga computacional que proporciona detecção de temporização de símbolo OFDMA e detecção de erro de freqúência mediante processamento diferencial dos elementos de seqúência do sinal de canal de sincronização (1112) e detecção de informação específica de célula e detecção de limite de quadro (1114), em um sistema OFDMA suportando múltiplas larguras de banda de sistema, ambos os sistemas, sincronizado e não sincronizado, um índice de célula grande e uma estrutura de símbolo OFDMA com ambos, comprimento de prefixo cíclico curto e longo.
