Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle antenna systems for mobile communication lack efficient methods for cooperative channel estimation and data communication, particularly in scenarios where multiple antennas are distributed and need to adapt to changing radio conditions and vehicle movement.
Innovation Solution
A transceiver system that divides antennas into subgroups for channel estimation and data communication, using a control device to determine radio channel information between subgroups and adaptively select antennas based on vehicle direction and radio conditions, enabling predictive channel estimation and improved data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are used for both channel estimation and data communication, then antenna utilization is improved, but channel estimation accuracy deteriorates due to lack of spatial separation
Solution Approach 1:
The patent divides the multiple antennas into two distinct subgroups: a first subgroup dedicated to channel estimation and a second subgroup dedicated to data communication. This segmentation allows each subgroup to perform its specific function optimally without interference, resolving the contradiction between antenna utilization and estimation accuracy by assigning specialized roles to different antenna sets.
2Reliability
If antennas are distributed at different locations on the vehicle, then spatial diversity is improved, but system complexity increases due to coordinated control requirements
Solution Approach 1:
By segmenting antennas into spatially separated subgroups with dedicated functions, the patent exploits spatial diversity for improved reliability. The first subgroup at certain locations performs channel estimation while the second subgroup at different locations handles data communication, creating spatial separation that enhances diversity without requiring complex coordinated control between all antennas.
Solution Approach 2:
The patent applies local quality by assigning different functional characteristics to different antenna subgroups based on their spatial locations. The first subgroup is optimized for channel estimation tasks while the second subgroup is optimized for data communication, allowing each local antenna set to have specialized properties suited to its specific function and location.
3Reliability
If channel estimation is performed using all available antennas, then estimation reliability is improved, but data communication capacity is reduced due to antenna resource consumption
Solution Approach 1:
The patent resolves this resource allocation contradiction by segmenting the antenna resources: the first subgroup of antennas is dedicated to channel estimation tasks, ensuring reliable estimation, while the second subgroup is dedicated to data communication, ensuring adequate communication capacity. This segmentation allows both functions to operate simultaneously with sufficient resources without competing for the same antenna elements.
