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.

AI Technical Summary

Benefits of technology

The patent text describes methods and systems for transmitting voice, video, and data information simultaneously in both directions on a single center frequency, bandwidth, and radiation polarity using a special corridor. This results in a doubled efficiency of the communications spectrum, which means that more data can be transmitted using the same frequency and the same amount of bandwidth as compared to transmitting in only one direction. The method can be applied to both FDD and TDD systems, and the efficiency is increased proportional to the ratio of data in both directions or by allowing continuous simultaneous transmission in both directions.
