Receiver Antenna Diversity Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio receivers with receiver antenna diversity consume more power, reducing the operation time of user radio terminals with battery power sources, as they are more complex and require increased energy consumption.
Innovation Solution
An apparatus and method that include an interface to obtain information on a power control procedure and a processing unit to switch the receiver antenna diversity branch on or off based on a comparison with predetermined conditions, optimizing power usage by enabling or disabling the diversity branch according to reception quality indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receiver antenna diversity is used, then signal quality and network capacity are improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the receiver antenna diversity configuration adjustable rather than fixed. The system dynamically switches between diversity mode and single-antenna mode based on real-time signal quality assessments, allowing the receiver to adapt its complexity to current operating conditions and optimize the balance between signal quality and power consumption.
Solution Approach 2:
The patent changes the operational parameter of the receiver by switching between different antenna configurations. When signal quality exceeds a predetermined threshold, the system changes from using multiple antennas (diversity mode) to using a single antenna, thereby reducing power consumption while maintaining adequate signal quality.
2Productivity
If receiver antenna diversity is used, then network capacity and service coverage are improved, but operation time of battery-powered terminals is reduced
Solution Approach 1:
The system dynamically adjusts its operational mode based on signal conditions. When signal quality is sufficient (above threshold), the receiver operates in power-saving single-antenna mode, extending battery operation time. When signal quality degrades, it switches to diversity mode to maintain network capacity and coverage, thus optimizing the trade-off between productivity and duration of action.
Solution Approach 2:
The patent implements periodic assessment of signal quality conditions to determine when to switch between diversity and single-antenna modes. This periodic monitoring and switching allows the system to maintain network capacity when needed while minimizing power consumption during favorable conditions, thereby extending overall operation time.
