Este artigo propõe um cancelador de ruído adaptativo com baixa distorção de sinal na presença de crosstalk. O cancelador de ruído proposto possui dois pares de filtros adaptativos de acoplamento cruzado, cada um dos quais consiste no filtro principal e um subfiltro. As relações sinal-ruído (SNRs) dos sinais primário e de referência são estimadas pelos subfiltros. Para reduzir a distorção do sinal na saída do cancelador de ruído adaptativo, os tamanhos dos passos para adaptação dos coeficientes nos filtros principais são controlados de acordo com os SNRs estimados. Os resultados da simulação computacional mostram que o cancelador de ruído proposto reduz a distorção do sinal de saída em até 15 dB em comparação com o cancelador de ruído convencional.

Abstract: This paper proposes an adaptive noise canceller with low signal-distortion in the presence of crosstalk. The proposed noise canceller has two pairs of cross-coupled adaptive filters, each of which consists of the main filter and a sub filter. The signal-to-noise ratios (SNRs) of the primary and the reference signals are estimated by the sub filters. To reduce signal distortion at the output of the adaptive noise canceller, the step sizes for coefficient adaptation in the main filters are controlled according to the estimated SNRs. Computer simulation results show that the proposed noise canceller reduces signal distortion in the output signal by up to 15 dB compared to the conventional noise canceller.
