Time Offset Encoding for Multi-Frequency Signal Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal processing techniques in wired and wireless communication require subdividing bandwidth, leading to limited capacity and congestion, as they struggle to support a large number of logical channels without increasing bandwidth or reducing channel share.
Innovation Solution
The method employs unique time offsets for each logical channel on shared signal frequencies, allowing all standard signal properties to be used concurrently, enabling efficient multiplexing of multiple channels without interleaving or subdividing bandwidth, and is compatible with existing modulation and demodulation techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If bandwidth is subdivided to support multiple logical channels, then the number of channels increases, but bandwidth becomes a limited shared resource subject to congestion and exhaustion
Solution Approach 1:
The patent introduces a time dimension to frequency-based communication by applying unique time offsets to each logical channel's signal across multiple frequencies. This transforms the traditional two-dimensional frequency allocation into a three-dimensional space-frequency-time domain, allowing channels to coexist without bandwidth subdivision while maintaining distinct separation through temporal positioning.
2Quantity of substance
If more frequencies are used to support larger number of channels, then channel capacity increases, but bandwidth resource becomes more limited and congested
Solution Approach 1:
The patent merges multiple logical channels into a unified transmission framework where all channels share the same frequency resources simultaneously. By combining frequency and time dimensions, the system allows concurrent transmission of multiple channels over identical frequency bands, eliminating the need for frequency subdivision and maximizing bandwidth utilization efficiency.
3Quantity of substance
If time offsets are applied to each frequency for each logical channel, then channel separation is achieved without bandwidth subdivision, but signal processing complexity increases
Solution Approach 1:
The patent changes the temporal parameter of signal transmission by applying unique time offsets to each logical channel. This parameter transformation allows channel differentiation through time positioning rather than frequency division, enabling multiple channels to occupy the same frequency spectrum simultaneously while maintaining distinct identity through their temporal characteristics.

AI summary
A method of processing a signal including the steps of: (a) modulating the signal using a modulator corresponding to a modulation, (b) sending the modulated signal over multiple frequencies where the signal is offset in time in each frequency, (c) receiving the signal over the multiple frequencies, (d) reconstructing the sent signal by reversing the time delay and combining the received signal from each frequency, and (e) demodulating the received combined signal using a demodulator corresponding to the modulation used in (a).
