Dynamic Antenna Selection for Mobile Relay Signal Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in achieving optimal signal quality and system capacity due to the limited number of antennas in conventional wireless devices, which are not adequately optimized for complex digital communication systems, especially in vehicles where multiple antennas with different orientations and characteristics could enhance performance.
Innovation Solution
A transceiver apparatus and method that dynamically selects a subset of antennas based on performance criteria, using a control module to couple antennas with different orientations and polarizations to improve transmission characteristics, and includes a receiver module for measuring signal quality and a storage module for storing location-specific antenna performance data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a limited set of antennas is used in conventional wireless devices, then device complexity and cost are reduced, but signal quality and system capacity deteriorate
Solution Approach 1:
The patent implements dynamic antenna selection where the transceiver can switch between different antennas based on real-time signal conditions. The system dynamically couples antenna ports to different physical antennas from a larger set, allowing adaptation to changing radio environments without permanently configuring all antennas. This resolves the contradiction by providing high signal quality when needed while keeping the effective antenna count manageable through dynamic reconfiguration.
Solution Approach 2:
The patent makes antenna ports universal by enabling each port to be coupled to multiple different physical antennas through dynamic selection. Instead of dedicating one antenna per port, the system allows any antenna port to access any available antenna from the larger set, maximizing the utility of both the antenna ports and the physical antennas. This multi-functionality approach improves signal quality without proportionally increasing device complexity.
2Adaptability or versatility
If multiple antennas with different orientations and polarizations are used, then transmission characteristics and signal quality improve, but device complexity increases
Solution Approach 1:
The patent applies local quality by assigning different orientations and polarizations to different physical antennas, then selectively coupling them to antenna ports based on the specific communication needs. Each antenna maintains its unique characteristics (local quality), and the dynamic selection process matches the appropriate antenna properties to the current transmission requirements. This resolves the contradiction by providing diverse transmission characteristics without requiring all antennas to be permanently active or complexly configured.
