SYSTEMS AND METHODS FOR REDUCING EFFECTS OF LOCAL OSCILLATOR LEAKAGE

摘要

According to some embodiments, a receiving device: receives a radio frequency (RF) signal from a transmitting device over a wireless channel; performs a channel estimation of the wireless channel based on the RF signal; obtains a direct current (DC) bin measurement based on the channel estimation; determines a direct current (DC) offset correction based on the DC bin measurement; and sending the DC offset correction to the transmitting device via a local transmitter. The transmitting device: receives the DC offset correction information from the receiving device over a first wireless channel; receives data to be transmitted to the receiving device, where the DC offset correction information describing the DC offset correction; applies the DC offset correction to a transient signal that is based on the data; converts the transient signal to an RF signal; and transmits the RF signal to the receiving device over a second wireless channel.
