Abstract
A device includes a primary sector and secondary sectors communicatively coupled to the primary sector. The processor included in the primary sector is configured to down convert a Radio Frequency (RF) signals with a first frequency to an analog baseband (IQ) signal with a second frequency, and receive a second digital baseband signal that comprises a first digital baseband signal and a digital echo signal. The first digital baseband signal comprises a training sequence signal. Further, the processor estimates a plurality of filter taps of the FIR filter based on the digital echo signal and estimate the digital echo signal in the received second digital baseband signal based on the first digital baseband signal and the plurality of filter taps of the FIR filter. The estimated digital echo signal is removed from at least one current digital baseband signal based on the down conversion of the RF signals.
