Title:
EQUALIZER DIGITAL SELF-INTERFERENCE CANCELATION FOR MIMO TRANSMITTERS
Document Type and Number:
WIPO Patent Application WO/2022/215837
Kind Code:
A1
Abstract:
An apparatus is configured to perform a method for self-interference cancelation (SIC). In one embodiment, an apparatus is provided. The apparatus includes a transceiver, a first number of transmit antennas, a second number of receive antennas, an equalizer, and SIC circuitry. The equalizer is configured to, for at least one receive antenna of the second number of receive antennas: receive feedback signals, wherein a feedback signal is received from each of the first number of transmit antennas; and calculate, based on the feedback signals and an equalizer function, a self-interference (SI) estimate for the at least one receive antenna. The SIC circuitry is configured to, for the at least one receive antenna of the second number of receive antennas, subtract the SI estimate from a signal received at the at least one of the second number of receive antennas to obtain a residual signal.
