System and method for increased bandwidth efficiency within microwave backhaul of a telecommunication system

摘要

An apparatus for transmitting information in a wireless communication system includes a first interface for receiving a plurality of input data streams. Signal processing circuitry transmits and receives the plurality of input data streams on at least one frequency. Each of the plurality of input data streams on the at least one frequency have a different orbital angular momentum imparted thereto.

1. An apparatus for transmitting information in a wireless communications system, comprising:
a first interface for receiving a plurality of input data streams; signal processing circuitry for processing each of the received plurality of input data streams to apply a different orbital angular momentum to each of the plurality of input data streams, combining at least two of the plurality of input data streams each having the different angular momentum applied thereto onto a single RF frequency; a transmitter for transmitting the single RF frequency having the at least two input data streams, each with the different orbital angular momentums applied thereto over a radio frequency channel on the single RF frequency; a receiver for receiving the at least one frequency having the plurality of different orbital angular momentums therein over the radio frequency channel; signal separator circuitry for separating each of the plurality of input data streams having the different orbital angular momentum from the received single RF frequency; and second signal processing circuitry for removing the different orbital angular momentum from each of the plurality of input data streams.
