Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media systems are limited in coverage area and diversity performance due to restrictions on the number of transmitters and receivers, requiring careful frequency coordination and infrastructure setup, which hinders the efficient processing of a large number of audio channels.
Innovation Solution
A media system employing a maximum diversity scheme with antenna modules that wirelessly receive broadband RF signals, convert them into digital baseband components, and apply diversity processing to generate a single digital data stream, which is then output over a network cable, allowing for an unlimited number of receiver antennas to be deployed without coordination issues, thus enhancing coverage and diversity performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional media systems use limited transmitters and receivers with frequency coordination, then system complexity is controlled, but coverage area and diversity performance are restricted
Solution Approach 1:
The patent replaces the conventional RF-based mechanical/electromagnetic coordination system with a digital baseband processing system. Each antenna module independently converts RF signals to digital baseband components and processes them locally, eliminating the need for complex RF frequency coordination between multiple transmitters and receivers. This substitution of the processing domain from RF to digital baseband resolves the contradiction by allowing unlimited antenna deployment without proportional increase in system complexity.
Solution Approach 2:
The system segments the signal processing function into independent antenna modules, where each module handles its own RF-to-digital conversion and diversity processing autonomously. This segmentation allows each module to operate independently without coordinating with other modules at the RF level, enabling scalable deployment that improves coverage area without linearly increasing overall system complexity.
2Reliability
If unlimited receiver antennas are deployed in conventional systems, then diversity performance improves, but antenna phase interactions and RF interference occur
Solution Approach 1:
The patent eliminates antenna phase interactions and RF interference by substituting the RF combining approach with digital baseband processing. Each antenna's signal is independently converted to digital baseband components before any combining operations, which occurs in the digital domain rather than the RF domain. This prevents the harmful interactions that occur when multiple RF signals are combined, allowing unlimited antennas to be deployed while maintaining high diversity performance.
Solution Approach 2:
The digital baseband conversion acts as an intermediary between the RF antenna signals and the final combined output. By introducing this intermediate digital processing stage, the system avoids direct RF interaction between multiple antenna signals, thereby eliminating phase interactions and RF interference while still achieving diversity combining through digital processing of the baseband components.
3Productivity
If more transmitters are added to increase audio channel capacity, then productivity improves, but system complexity and coordination requirements increase
Solution Approach 1:
The system segments audio channel processing across multiple independent antenna modules, where each module handles its own set of RF signals and converts them to digital baseband components. This segmentation allows the system to scale audio channel capacity by simply adding more independent modules without increasing the complexity of frequency coordination, as each module operates autonomously in the digital baseband domain.
Solution Approach 2:
Each antenna module is designed as a universal, multi-functional unit that can process any RF input signals and convert them to digital baseband components. This universality allows the system to handle a large number of audio channels by deploying identical modular units, avoiding the need for specialized coordination infrastructure that would increase system complexity as channel capacity scales.
