본 논문에서는 ISI(Inter-Symbol Interference) 효과를 완화하고 허용 가능한 데이터 전송률을 높이기 위한 새로운 타이밍 및 위상 복구 알고리즘을 제안합니다. 어떤 심볼 레이트가 전송되든 상관없이 채널의 평균 초과 지연을 샘플링을 위한 타이밍 순간으로 사용하고, 해당 순간에 샘플링된 복소 기저대역 임펄스 응답의 위상을 보상을 위한 반송파 위상으로 사용합니다. 채널의 평균 초과 지연은 데이터 전송 속도와 무관하며 채널 지연 확산보다 긴 기호 간격으로 낮은 속도의 데이터 시퀀스를 전송함으로써 기존의 타이밍 복구 회로로 추정할 수 있습니다. 타이밍 및 위상 복구에 제안된 알고리즘을 적용한 경우와 적용하지 않은 경우의 전송 성능을 수치적으로 비교했습니다. 또한 DFE의 입력을 기존 방식과 제안 방식으로 샘플링한 경우 DFE(Decision Feedback Equalizer)의 전송 성능을 비교한다. 우리는 새로운 계획이 더 나은 성능을 가지고 있음을 발견했습니다. 기존 방법과 비교해 BER 임계값 10에서 정규화된 허용 데이터 속도-5 2% 미만의 정전 확률은 5배 증가할 수 있습니다. 새로운 방식을 DFE와 함께 사용하면 성능이 더욱 향상될 수 있습니다. 시뮬레이션된 채널과 물리적 채널 모두에 대한 시뮬레이션 결과는 새로운 방식의 효율성을 검증했습니다.

Abstract: In this paper we propose a new timing and phase recovery algorithm to mitigate the inter-symbol interference (ISI) effect and to increase the permissible data rate. We use the mean excess delay of the channel as the timing instant for sampling no matter what symbol rates are transmitted and use the phase of the complex baseband impulse response sampled at the corresponding instant as the carrier phase for compensation. The mean excess delay of a channel is independent of the data transmission rates and can be estimated by the conventional timing recovery circuit by transmitting a low rate data sequence with symbol interval longer than the channel delay spread. We have numerically compared the transmission performances without and with applying our proposed algorithm in the timing and phase recovery. We also compare the transmission performance of the decision feedback equalizer (DFE) when the inputs to the DFE are sampled by the conventional method and by our proposed method. We found that the new scheme has a better performance. Compare with the conventional method, the normalized permissible data rate at a BER threshold of 10-5 and an outage probability of less than 2% can be increased by 5 times. While the new scheme is employed together with DFE, the performance can be further improved. Simulation results for both simulated and physical channels have verified the effectiveness of the new scheme.
