1Productivity
If conventional modulation techniques (AM, FM, QAM, QPSK, PSK) are used to increase data throughput, then data transmission capability is improved, but power usage efficiency and bandwidth efficiency deteriorate
Solution Approach 1:
The patent segments the data transmission process by embedding message waveforms within segments of conventional modulated signals. The carrier signal is divided into multiple time slots, with each slot containing a portion of the message waveform. This segmentation allows the system to maintain high data throughput while improving power efficiency by transmitting data in discrete, manageable portions rather than continuously at full power.
Solution Approach 2:
The patent applies nesting by embedding the message waveform within the conventional modulated signal structure. The message waveform is nested inside the carrier signal time slots, allowing the system to utilize the existing signal framework while adding hidden data layers. This nested structure enables increased data throughput without requiring completely new transmission infrastructure, thereby improving power usage efficiency.
2Productivity
If conventional modulation techniques are used to increase data throughput, then data transmission capability is improved, but spectral efficiency and error rates deteriorate
Solution Approach 1:
The patent introduces the message waveform as an intermediary element that is embedded within the conventional modulated signal. This intermediary approach allows the system to separate the data transmission function from the carrier signal, enabling better error control and signal processing. The message waveform acts as a mediator that can be independently processed and corrected, reducing overall error rates while maintaining high data throughput.
Solution Approach 2:
The patent adds a temporal dimension to the data transmission by embedding message waveforms within specific time slots of the carrier signal. This dimensional approach allows multiple data streams to be transmitted simultaneously without interfering with each other, improving spectral efficiency. The time-domain separation creates additional processing dimensions for error correction and signal optimization.
3Reliability
If signal degradation occurs during transmission, then transmission distance is limited, but increasing transmission power improves signal quality
Solution Approach 1:
The patent applies partial action by transmitting only the necessary portion of the message waveform within each time slot rather than transmitting the entire signal at full power continuously. This partial transmission approach reduces energy consumption while maintaining sufficient signal quality for reliable data recovery. The system transmits data in optimized portions that balance signal strength and energy efficiency.
Solution Approach 2:
The patent utilizes parameter changes by varying the embedding depth and timing of message waveforms within the carrier signal. By adjusting these parameters, the system can optimize signal quality without requiring proportional increases in transmission power. The parameter optimization allows for better signal-to-noise ratio management, improving reliability without excessive energy consumption.

AI summary
A method for embedding message waveforms within conventionally modulated signals includes receiving input digital data and generating, based upon the input digital data, auxiliary waveform data encoding the input digital data. The auxiliary waveform data represents an auxiliary waveform wherein phase shifts within selected periods of the auxiliary waveform relative to a carrier signal encode the input digital data within the auxiliary waveform. The auxiliary waveform data is mixed with modulation data representing a modulation signal so as to produce a multi-component signal.
