Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional communication systems use fixed modulation sets, then hardware complexity is reduced, but adaptability to changing channel conditions deteriorates
Solution Approach 1:
The patent replaces hardware-based modulation switching with software-defined radio technology. A programmable processor dynamically selects and applies different modulation sets (including spiral-based modulations) based on channel conditions, eliminating the need for multiple dedicated hardware modulation circuits. This software substitution provides full adaptability while maintaining simple hardware architecture.
Solution Approach 2:
The patent implements a universal software-defined radio platform that can perform multiple modulation functions (QAM, PSK, spiral modulations, etc.) using a single reconfigurable system. The programmable processor loads different modulation algorithms from memory and applies them as needed, making one hardware system capable of performing the functions of many specialized systems.
2Reliability
If spiral-based communications use multiple modulation sets, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic modulation set selection where the system continuously monitors channel conditions and adaptively switches between different modulation sets (including various spiral-based modulations with different growth rates and symbol rates). This dynamic adaptation ensures optimal communication performance while minimizing power consumption by selecting the most efficient modulation set for current conditions rather than operating at fixed high performance settings.
Solution Approach 2:
The patent changes operational parameters (modulation type, symbol rate, growth rate g) based on channel conditions. When channel quality is good, higher-order modulations are used for maximum throughput; when conditions deteriorate or power is constrained, the system switches to more robust lower-order modulations or reduces symbol rates, thereby maintaining performance while reducing power consumption.
3Adaptability or versatility
If software-defined radios store thousands of modulation sets, then adaptability is enhanced, but memory requirements and device complexity increase
Solution Approach 1:
The patent stores modulation sets as digital data (mathematical parameters, lookup tables, or algorithmic descriptions) in programmable memory rather than implementing each modulation as separate hardware circuitry. The processor loads and executes software representations of different modulation schemes, including spiral-based modulations characterized by parameters like growth rate g and symbol rate. This digital copying approach enables storage of thousands of modulation sets with minimal memory requirements compared to hardware implementation.
Data Source
AI summary
A software defined radio is disclosed. The software defined radio may utilize a method for encoding a bit stream into non-periodic spiral-based symbol waveforms for transmission and reception. The method includes transmitting a signal constructed from one or more non-periodic modulation sets residing on a memory system of the software defined radio, where each modulation set corresponds to a symbol alphabet and provides non-periodic symbol waveforms corresponding to symbol bit sequences segmented by a microprocessor according to alphabet size. The method also includes receiving the signal constructed from one or more spiral modulation sets, wherein the signal from one or more spiral modulation sets are filtered and then fed to an analog to digital converter, where the signal constructed from the one or more spiral modulation sets is digitized and are fed to the microprocessor. A non-transitory computer storage media may also execute the method.
