Abstract
Disclosed are methods, systems, and apparatus for maximizing the spectral efficiency of a communications spectrum by providing a means to transmit information continuously in both directions of a radio link on the same center frequency at any given time. One embodiment may be directed to a method of communicating in a point-to-point radio system. The method may include receiving a first signal at a first antenna of a radio head. The first signal may include a transmitted data signal and interfering signals. The method continues by determining a correction signal from a transmitter of the radio head and processing the first signal to remove the interfering signals using the correction signal, and sending a second signal using a second antenna. The first and second signals may be sent and received at substantially the same time.
