摘要

本文分析了抗串扰自适应消噪器的性能。CTRANC系统的对称结构导致在处理不同入射角的噪声时性能不一致。为了解决这个问题，提出了一种在主信道上使用延迟单元的非对称CTRANC (ACTRANC)结构。ACTRANC允许在先进的通信应用中灵活地对准噪声源与传感器阵列，如自适应噪声消除、声学回声消除和自适应波束形成。

Principle and applications of asymmetric crosstalk-resistant adaptive noise canceller

This paper analyzes the performance of the crosstalk-resistant adaptive noise canceller (CTRANC). The CTRANC system's symmetric structure causes inconsistent performance when treating noise coming from different incident angles. To solve this problem, an asymmetric CTRANC (ACTRANC) structure using a delay unit on the primary channel is proposed. The ACTRANC allows flexible alignment of the noise source with the sensor array in advanced communication applications such as adaptive noise cancellation, acoustic echo cancellation and adaptive beamforming.
