Este artigo propõe um cancelador de interferência multipercurso (MPIC) para canais multiplexados de código ortogonal no link direto W-CDMA e avalia por simulação computacional a melhoria no desempenho do BER devido ao efeito de supressão de interferência multipercurso (MPI) obtido pelo MPIC. Os resultados da simulação mostram que um MPIC de um estágio, que remove o MPI do canal piloto comum (PICH), canal de controle comum (CCH) e canal de sincronização (SCH), atinge um efeito de supressão de MPI suficiente e que o sinal recebido necessário Eb/N0 do canal de tráfego (TCH) no BER médio de 10-3 usar o MPIC para os canais comuns é diminuído em aproximadamente 6.5 dB em comparação com aquele com um receptor Rake baseado em filtro casado (MF) (a relação de potência de transmissão de cada canal comum para TCH: ΔPICH/TCH=0dB,ΔCCH/TCH=5dB,ΔSCH/TCH=3 dB, sem controle de potência de transmissão rápida (TPC) e recepção de diversidade de antena). Também mostramos que usando MPIC, a transmissão necessária Eb/N0 no BER médio de 10-3, quando a proporção do alvo Eb/I0 dos 9 usuários interferentes para o usuário desejado é ΔInt/Des=6 dB com TPC rápido, aumenta apenas aproximadamente 0.6 dB em comparação com quando ΔInt/Des=0dB. Isto implica que a supressão preferencial de MPI de TCHs de alta taxa que reduz o aumento de complexidade num terminal móvel é eficaz no aumento da capacidade da ligação na ligação directa.

Abstract: This paper proposes a multipath interference canceller (MPIC) for orthogonal code multiplexed channels in the W-CDMA forward link and evaluates by computer simulation the improvement in BER performance owing to the multipath interference (MPI) suppression effect obtained by the MPIC. The simulation results show that a one-stage MPIC, which removes the MPI from the common pilot channel (PICH), common control channel (CCH), and synchronization channel (SCH), achieves a sufficient MPI suppression effect, and that the required received Eb/N0 of the traffic channel (TCH) at the average BER of 10-3 using the MPIC for the common channels is decreased by approximately 6.5 dB compared to that with a matched filter (MF)-based Rake receiver (the transmit power ratio of each common channel to TCH: ΔPICH/TCH=0 dB, ΔCCH/TCH=5 dB, ΔSCH/TCH=3 dB, without fast transmit power control (TPC) and antenna diversity reception). We also show that by using MPIC, the required transmit Eb/N0 at the average BER of 10-3, when the ratio of the target Eb/I0 of the 9-interfering users to desired user is ΔInt/Des=6 dB with fast TPC, is increased by only approximately 0.6 dB compared to that when ΔInt/Des=0 dB. This implies that the preferential MPI suppression from high-rate TCHs that abates the increase in complexity in a mobile terminal is effective in increasing the link capacity in the forward link.
