Abstract
A method and electronic device for leakage cancellation. The electronic device includes a first antenna pair, a memory, and a processor. The first antenna pair includes a first transmitter antenna configured to transmit signals and a first receiver antenna configured to receive signals. The memory is configured to store data. The processor is configured to identify, from the data stored in the memory, a first leakage factor associated with at least the first antenna pair, control the first transmitter antenna to transmit a first signal, generate a first CIR based on receipt, by the first receiver antenna, of reflection of the first signal, determine leakage in the first CIR based on at least the identified first leakage factor, and cancel the determined leakage from the first CIR.
