본 논문에서는 W-CDMA 순방향 링크에서 직교 코드 다중화된 채널을 위한 다중 경로 간섭 제거기(MPIC)를 제안하고, MPIC에 의해 획득된 다중 경로 간섭(MPI) 억제 효과로 인한 BER 성능 향상을 컴퓨터 시뮬레이션을 통해 평가합니다. 시뮬레이션 결과에서는 PICH(Common Pilot Channel), CCH(Common Control Channel), SCH(Synchronization Channel)에서 MPI를 제거한 1단 MPIC가 충분한 MPI 억제 효과를 얻을 수 있으며, 필요한 수신 Eb/N0 평균 BER 10의 트래픽 채널(TCH)-3 공통 채널에 MPIC를 사용하는 것은 MF(Matched Filter) 기반의 Rake 수신기에 비해 약 6.5dB 감소합니다. (각 공통 채널의 TCH에 대한 전송 전력 비율: Δ피치/티치=0dB, ΔCCH/TCH=5dB, ΔSCH/TCH=3dB, 빠른 전송 전력 제어(TPC) 및 안테나 다이버시티 수신 없음). 우리는 또한 MPIC를 사용함으로써 필요한 전송을 보여줍니다. Eb/N0 평균 BER 10에서-3, 목표 비율이 Eb/I0 원하는 사용자에 대한 9명의 방해 사용자 중 Δ는정수/목적어=6dB(빠른 TPC 사용)는 Δ일 때와 비교하여 약 0.6dB만 증가합니다.정수/목적어=0dB. 이는 이동 단말의 복잡성 증가를 완화하는 고속 TCH의 우선적 MPI 억제가 순방향 링크의 링크 용량을 증가시키는 데 효과적이라는 것을 의미합니다.

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.
