Abstract
Un método para proporcionar diversidad de transmision para un canal de sincronizacion secundario (S-SCH) consiste en generar una senal S-SCH, realizar un proceso de diversidad de transmision de conmutacion de frecuencia (FSTD) en una senal S-SCH para crear una primera senal procesada, realizar un proceso de conmutacion de vectores de precodificacion (PVS) en la primera senal procesada para crear una senal S-SCH procesada, y transmitir la senal S-SCH procesada.
