Abstract
A method of reducing the noise from a transmitter at an associated receiver is disclosed. Noise contributions in active channels are identified and used to update a shared noise cancellation filter. Excluding signals from inactive channels speeds up the filter convergence to a near optimal solution. Sharing a filter across multiple channels reduces component count and power consumption.
