Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MIMO communication systems with multiple antennas face challenges in achieving high-speed communication due to uneven noise distribution within devices, particularly when high-speed interfaces like SDI or HDMI are close to antennas, leading to self-interference noise that previous methods fail to adequately address.
Innovation Solution
A communication apparatus with multiple antennas, including a detection unit to assess the communication status and a specifying unit to identify noise components in received signals, allowing for the adjustment of transmission power to maintain balanced signal-to-noise ratios across antennas, thereby reducing the impact of uneven noise distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple antennas are used for MIMO communication, then communication speed is improved, but uneven noise distribution from nearby high-speed interfaces degrades signal quality
Solution Approach 1:
The patent adjusts transmission power parameters for each antenna based on detected noise levels. The control unit modifies power allocation dynamically to compensate for uneven noise distribution, thereby maintaining signal quality while utilizing multiple antennas for high-speed communication
Solution Approach 2:
The detection unit continuously monitors noise levels from nearby high-speed interfaces and feeds this information back to the control unit. This feedback mechanism enables real-time adjustment of transmission power to maintain optimal signal-to-noise ratio across all antennas
2Reliability
If transmission power is increased to overcome noise, then signal quality is improved, but energy consumption increases
Solution Approach 1:
The patent dynamically adjusts transmission power parameters based on actual noise conditions detected by the detection unit. Instead of using fixed high power, the system optimizes power allocation to match actual signal quality requirements, reducing unnecessary energy consumption while maintaining signal quality
3Volume of moving object
If antennas are positioned closer to high-speed interfaces for compact design, then device size is reduced, but self-interference noise increases
Solution Approach 1:
The detection unit monitors noise levels generated by nearby high-speed interfaces and provides feedback to the control unit. This enables real-time detection and compensation of self-interference noise, allowing compact antenna placement without sacrificing communication quality
Solution Approach 2:
The system adjusts transmission power parameters compensatorily based on detected self-interference noise levels. By increasing power for affected antennas dynamically, the system maintains communication performance despite compact positioning that causes higher self-interference
