Abstract :
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
