Neste artigo, é proposto um método de Controle de Potência de Transmissão (TPC) para Multiplexação por Divisão de Frequência Ortogonal Acesso Múltiplo por Divisão de Código de Sequência Direta (OFDM-DS-CDMA), a fim de compensar a atenuação de potência em cada subportadora. Em vez de atribuir os mesmos níveis de potência para todas as subportadoras, diferentes níveis de potência de transmissão são atribuídos a diferentes subportadoras, de acordo com a atenuação das subportadoras. O desempenho do sistema, em termos de Taxa de Erro de Bit (BER), foi avaliado por simulação de Monte Carlo. Os resultados da simulação apresentaram melhoria significativa, o sistema proposto teve um desempenho muito melhor que o sistema sem TPC. É mostrado que Each Carrier TPC tem melhor desempenho do que All Carriers TPC, onde todas as operadoras são controladas uniformemente, portanto, Each Carrier TPC é mais adequado para o sistema OFDM-DS-CDMA.

Abstract: In this paper, a method of Transmission Power Control (TPC) for Orthogonal Frequency Division Multiplexing Direct Sequence Code Division Multiple Access (OFDM-DS-CDMA), in order to compensate for power attenuation at each subcarrier, is proposed. Instead of assigning same power levels for all-subcarriers, different transmission power levels are assigned to different subcarriers, according to the attenuation of the subcarriers. System performance, in terms of Bit Error Rate (BER), has been evaluated by Monte Carlo simulation. The simulation results presented significant improvement, the proposed system performed much better than the system without TPC. It is shown that the Each Carrier TPC performs better than All Carriers TPC, which all carriers are controlled uniformly, hence Each Carrier TPC is more suitable for OFDM-DS-CDMA system.
