Embodiment Construction

[0015] The present disclosure is directed to a distributed beamforming system including a plurality of user terminals and platform terminals. The platform terminal includes an antenna array having a plurality of antenna elements, where each antenna element emits a wide area beam that surrounds all user terminals that are part of the distributed beamforming system. The platform terminal transmits multiple individual wireless signals that are orthogonal with respect to each other based on frequency, time or through coding techniques. It should be understood that there is a one-to-one mapping of each individual wireless signal to each antenna element located on the platform terminal. Each individual user terminal receives an individual radio signal. The user terminal applies amplitude weights and phase shifts to each individual radio signal. The individual wireless signals are then combined together at individual user terminals to generate beamformed signals. It should be unde...

Abstract

The invention discloses a distributed beamforming system with user side beamforming processing. A distributed beamforming system includes a platform terminal and a plurality of user terminals. The platform terminal includes an antenna array including a plurality of antenna elements. Each antenna element transmits a wide-area beam configured to encompass each of the plurality of user terminals. The platform terminal also includes one or more processors in electronic communication with the antenna array and a memory coupled to the one or more processors. The memory stores data into a database and program code that, when executed by the one or more processors, causes the platform terminal to receive an incoming signal and split the incoming signal into a plurality of individual wireless signals. Each individual wireless signal corresponds to one of the plurality of antenna elements of the antenna array. The system also transmits the plurality of individual wireless signals to the user terminal by the antenna array.

Description

technical field [0001] The present disclosure relates to a distributed beamforming system. More specifically, the present disclosure is directed to a distributed beamforming system having a platform terminal that includes a phased array of antenna elements and a plurality of user terminals, where each user terminal generates a beamformed signal. Background technique [0002] Beamforming is a signal processing technique that directs the radiation pattern produced by an array of antenna elements toward a receiving device rather than spreading the radiation pattern in all directions. Multiple access beamforming payloads allow multiple receiving devices to share the allocated spectrum. If the receiving device is capable of movement, the system may require the beam to track the receiving device's movement, or to employ a priori known or communicated geometry. [0003] Existing solutions employ airborne beamforming or ground-based beamforming at the gateway side. When the beamf...
