Ultra-Wideband Signal Receiver Control for Low-Power Channel Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing channel estimation methods in UWB signal receivers consume excessive power due to all processing modules remaining active, leading to inefficient resource utilization.
Innovation Solution
A UWB signal receiver design that dynamically controls the activation of processing modules based on the strongest path of the received signal, using a control signal to turn off unnecessary modules during channel estimation, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all processing modules remain active during channel estimation, then channel estimation can be performed, but power consumption increases excessively
Solution Approach 1:
The signal processing unit is divided into multiple processing modules that can be independently controlled. The patent segments the processing functionality so that only the necessary modules are activated during channel estimation, while others remain inactive, thereby reducing overall power consumption while maintaining estimation effectiveness.
Solution Approach 2:
The patent implements dynamic control of processing module activation states. A control signal is generated based on the strongest path index to dynamically switch modules between active and inactive states. This dynamic adaptation allows the system to optimize power consumption according to actual channel estimation requirements rather than keeping all modules permanently active.
2Productivity
If all processing modules are activated, then processing capability is maximized, but resource utilization efficiency decreases
Solution Approach 1:
Instead of activating all processing modules (excessive action), the patent applies partial action by activating only the necessary modules for channel estimation. The control signal determines which specific modules are needed based on the strongest path identification, avoiding wasted resources on unnecessary processing while maintaining sufficient capability.
Solution Approach 2:
The patent changes the operational parameters of the processing modules by switching them between different states (active/inactive) based on the strongest path index. This parameter change allows the system to adjust resource allocation dynamically, improving utilization efficiency by matching processing capacity to actual needs rather than maintaining maximum capability continuously.

AI summary
An embodiment of the present application provides an ultra-wide band (UWB) signal receiver, including: a signal processing unit, configured to perform correlation processing on sampled discrete received signals to obtain a first processing result; a determination unit, configured to capture the first processing result and determine an index value corresponding to the strongest path of the received signal; and a channel estimation unit, configured to generate a control signal according to the index value.
