An electronic device is designed with multiple communication circuits and processors to receive and process reflection signals from various bands, calculating channel impulse responses and integrating them based on frequency characteristics, thereby enabling the acquisition of a channel impulse response in a wider band without the need for additional elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple channel impulse responses from different frequency bands are integrated to expand sensing bandwidth, then sensing resolution is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple channel impulse responses from different frequency bands (first and second bands) into a single integrated channel impulse response. The processor receives channel impulse responses from multiple communication circuits operating at different frequencies and combines them to create an enhanced sensing capability with expanded bandwidth, thereby improving sensing resolution without requiring separate processing paths for each frequency band.
Solution Approach 2:
The processor is designed to perform multiple functions: it processes channel impulse responses from different frequency bands, integrates them, and enables enhanced sensing capabilities. This multi-functional approach allows a single processor to handle diverse frequency band data and provide unified sensing output, reducing the need for separate dedicated processing units for each frequency band.
2Adaptability or versatility
If multiple communication circuits are used to receive signals from different bands, then sensing bandwidth is expanded, but the number of components increases
Solution Approach 1:
The patent combines multiple communication circuits operating at different frequency bands under a single processor that integrates their channel impulse responses. Rather than having separate processing chains for each frequency band, the system merges the data processing function into one unified processor, reducing the overall number of discrete components while maintaining the ability to receive and process signals from multiple bands.
Solution Approach 2:
The processor is designed as a multi-functional unit that handles channel impulse response processing for multiple frequency bands simultaneously. This universal processor replaces what would otherwise require multiple separate processing circuits, reducing component count while enabling expanded sensing bandwidth through multi-band signal integration.

AI summary
An electronic device is provided. The electronic device includes a first communication circuit, a second communication circuit, and at least one processor. The first communication circuit is configured to receive, in a first band, a first reflective signal reflected by an object, and obtain, based on the received first reflective signal, a first channel impulse response corresponding to the first reflective signal. The second communication circuit is configured to receive, in a second band, a second reflective signal reflected by the object, obtain, based on the received second reflective signal, a second channel impulse response corresponding to the second reflective signal, and obtain a third channel impulse response based on a first calculation using the second channel impulse response, a first central frequency of the first band and a second central frequency of the second band.
