Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite beamforming processes are computationally intensive, leading to increased hardware costs and reduced speed due to the need for complex processing and large data handling, particularly when handling a large number of beams and frequency channels.
Innovation Solution
The implementation of multiple beamforming split switches, each handling a portion of the frequency range, reduces processing requirements and data handling, allowing for efficient calculation of transmit signals using a single linear combination based on a transform table derived from receive beamforming coefficients, connection matrices, and transmit beamforming coefficients.

Engineering Contradiction Analysis
1Adaptability or versatility
If complex processing and large data handling are used to handle multiple beams and frequency channels, then beamforming capability is improved, but hardware costs increase and processing speed decreases
Solution Approach 1:
The patent divides the beamforming processing into separate functional blocks: receive beamforming coefficients calculation, connection matrix establishment, and transmit beamforming coefficients calculation. Each block processes specific portions of the data independently, reducing the computational burden on any single processing unit and lowering hardware requirements while maintaining the ability to handle multiple beams and frequency channels.
2Adaptability or versatility
If complex processing and large data handling are used to handle multiple beams and frequency channels, then beamforming capability is improved, but processing speed decreases
Solution Approach 1:
The patent segments the beamforming computation into distinct stages that can be executed in sequence or parallel. By calculating receive beamforming coefficients separately from transmit beamforming coefficients and using a connection matrix to link them, the system reduces the computational complexity at any given moment, enabling faster processing while maintaining support for multiple beams and frequency channels.
3Adaptability or versatility
If large data handling is used to handle multiple beams and frequency channels, then beamforming capability is improved, but storage requirements increase
Solution Approach 1:
The patent divides the beamforming data into separate components: receive beamforming coefficients, connection matrices, and transmit beamforming coefficients. Each component is stored and processed independently, reducing the amount of data that needs to be held in memory simultaneously. This segmented approach allows the system to support multiple beams and frequency channels while minimizing storage requirements compared to handling all data in a single large structure.

AI summary
Receive signals may be combined to form receive beam signals at multiple receive frequency channels. The receive beam signals may be partitioned by receive frequency channel into multiple groups of receive beam signals, each group corresponding to a different frequency spectrum and the multiple groups including a first group and a second group. The first and the second group of receive beam signals may be communicated to a first and a second switch, respectively. The first and the second group of receive beam signals may be switched by the first switch and the second switch, respectively, to generate a first and a second group of transmit beam signals. Transmit beam signals that include the first and the second group of transmit beam signals may be combined to form transmit signals to be transmitted using corresponding transmit antenna elements to form one or more transmit beams at multiple transmit frequency channels.
