Multimode Receiver for Wireless Diversity Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices require a complex and expensive configuration with multiple receiver modules and receive paths to perform diversity reception of multiple communication services, such as Wi-Fi and cellular signals, due to the need for multiple antennas and receivers.
Innovation Solution
A wireless communication device with a reduced number of receive paths, utilizing multimode receivers and band/mode selectors, which can operate in multiple receive modes to receive signals from multiple communication services simultaneously, and a controller to manage these modes for efficient signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple receiver modules with multiple receive paths are used to perform diversity reception of multiple communication services, then signal reception capability and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The patent employs a single receiver module that can operate in multiple receive modes (first receive mode and second receive mode) to receive signals from different communication services (first communication service and second communication service). This multi-functional receiver replaces what would traditionally require separate dedicated receivers for each service, thereby reducing the number of receiver modules while maintaining the capability to perform diversity reception across multiple services.
Solution Approach 2:
The receiver module dynamically switches between different receive modes based on which communication service is being received. The system controls the receiver to operate in the first receive mode for the first communication service and in the second receive mode for the second communication service, enabling adaptive reconfiguration of the receiver to meet different service requirements without requiring separate fixed receivers for each service.
2Adaptability or versatility
If multiple receiver modules with multiple receive paths are used to receive signals of multiple communication services, then service coverage and versatility are improved, but manufacturing cost increases
Solution Approach 1:
The patent implements a universal receiver module capable of receiving multiple communication services through different receive modes. This single multi-functional receiver module can be manufactured and integrated more cost-effectively than multiple separate dedicated receiver modules, while still providing comprehensive service coverage for both the first and second communication services.
