Abstract

"CONTROLE DE POTêNCIA DE TRANSMISSãO CDMA EM CICLO DE CONTROLE VARIáVEL" Em sistema de controle de potência de transmissão CDMA para controlar potência de transmissão reversa de potência de transmissão reversa para uma estação móvel, um detetor de freq³ência Doppler (50) detecta freq³ência máxima Doppler usando símbolo piloto extraído do sinal de dados desejados per período de controle de potência de transmissão. Quando a freq³ência máxima Doppler for menor que uma freq³ência limite Doppler, o sistema realiza controle de laço fechado em um ciclo do período de controle de potência de transmissão. Por outro lado, quando a freq³ência Doppler for maior que a freq³ência limite Doppler, o sistema realiza controle de laço fechado em um ciclo de N vezes o período de controle de potência de transmissão no surgimento.
