Simultaneous bidirectional transmission for radio systems

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.

Benefits of technology

[0004]Embodiments disclosed herein are directed to methods, systems, and apparatus for maximizing the spectral efficiency of a communications spectrum by providing a means to transmit voice, video, and data information continuously and simultaneously in both directions of a radio link at any given time on a single center frequency, bandwidth, radiation polarity, and spatial corridor. Accordingly, the embodiments described herein simultaneously transmit and receive two signals using the same center frequency, bandwidth, and radiation polarity, in the opposing directions along the same special corridor, thereby doubling the spectral efficiency.
