Multiple Stream Decoder for Military Radio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing full-duplex voice communication systems in military radio applications require significant computational resources and hardware due to the use of multiple vocoders for simultaneous voice reception, making them costly and inefficient.
Innovation Solution
A method for decoding multiple data streams in a voice communication system, involving a vocoder with decoder modules, a parameter combining module, and a speech synthesizer, which combines speech coding parameters from multiple channels to produce blended audible speech, reducing the need for multiple vocoders and enhancing resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vocoders are used to achieve full-duplex collaboration, then simultaneous voice reception capability is improved, but hardware requirements and computational resources increase significantly
Solution Approach 1:
The patent combines multiple speech coding parameter sets from different vocoders into a single integrated set of combined speech coding parameters. This merging approach allows the system to process multiple voice streams through one vocoder instance rather than requiring separate vocoders for each stream, thereby reducing hardware requirements while maintaining full-duplex collaboration capability
Solution Approach 2:
The patent creates a universal vocoder architecture that can handle multiple speech coding parameter sets simultaneously. The single vocoder is designed to accept and process parameters from multiple sources (different voice streams), making it multi-functional and eliminating the need for dedicated vocoders for each communication channel
2Productivity
If multiple vocoders are deployed for full-duplex voice communication, then simultaneous voice processing is enabled, but computational resources are significantly consumed
Solution Approach 1:
The patent merges multiple speech coding parameter sets into a single combined parameter set that can be processed by one vocoder. This consolidation reduces the total computational load by eliminating redundant processing that would occur if separate vocoders handled each stream independently, thereby reducing energy consumption while maintaining simultaneous voice processing capability
Solution Approach 2:
The universal vocoder design processes multiple speech coding parameter sets through a single computational engine. This multi-functional approach allows the system to achieve simultaneous voice processing without the proportional increase in computational resources that would be required by multiple separate vocoders
Data Source
AI summary
A method is provided for decoding data streams in a voice communication system. The method includes: receiving two or more data streams having voice data encoded therein; decoding each data stream into a set of speech coding parameters; forming a set of combined speech coding parameters by combining the sets of decoded speech coding parameters, where speech coding parameters of a given type are combined with speech coding parameters of the same type; and inputting the set of combined speech coding parameters into a speech synthesizer.
