Abstract:
1. A method for cancelling transmitter interference in a transceiver, comprising: receiving, by an interference receiver, a part of radio frequency signal output from a transmitter, processing the received signals, and outputting a digital signal; performing an adaptive equalization in a time domain or in a frequency domain on the digital signal output from the interference receiver; delaying for a predetermined time of the digital signal output from a receiver; and subtracting the adaptive equalized digital signal from the delayed digital signal, wherein a Finite Impulse Response (FIR) or an Infinite Impulse Response (IIR) is used for filtration when the adaptive equalization is performed in the time domain, and wherein a Fast Fourier Transform (FFT), a frequency domain amplitude phase weighting, and an Inverse Fast Fourier Transform (IFFT) are used for filtration when the adaptive equalization is performed in the frequency domain.
