Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radio communication systems face challenges in enabling simultaneous transmission and reception of multiple users in the same frequency band without collisions, leading to inefficiencies in channel capacity and increased power and bandwidth requirements.
Innovation Solution
A radio system and waveform that break down information into sub-blocks with synchronization and phase reference information, dispersing them across multiple frequencies and time periods to enable virtually simultaneous transmission and reception, using a transceiver and processor to manage these sub-blocks and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple users transmit simultaneously in the same frequency band using conventional Aloha protocols, then channel capacity is increased, but collision probability increases and transmission reliability deteriorates
Solution Approach 1:
The patent segments a block of information into multiple sub-blocks, each containing synchronization information. These sub-blocks are dispersed across different time periods and frequencies, allowing simultaneous transmissions to be separated and reconstructed without complete collision loss.
Solution Approach 2:
The patent introduces additional dimensions (time dispersion and frequency distribution) to the transmission process. By scattering sub-blocks across multiple time periods and frequencies, the system transforms a single-dimension collision problem into a multi-dimensional reconstruction problem, enabling reliable recovery even when some sub-blocks collide.
2Reliability
If conventional Aloha protocols are used to avoid collisions through randomization, then transmission reliability is improved, but channel capacity and efficiency decrease
Solution Approach 1:
By dividing information into sub-blocks with synchronization capabilities, the system allows aggressive channel access without requiring conservative randomization delays. Each sub-block can be independently received and synchronized, enabling higher channel loading while maintaining reliability.
Solution Approach 2:
The synchronization information embedded in each sub-block provides feedback mechanisms that allow receivers to identify and reconstruct transmitted data even when collisions occur, eliminating the need for conservative retransmission protocols and improving channel efficiency.
3Productivity
If channel capacity is increased to handle more simultaneous transmissions, then productivity is improved, but peak power and bandwidth requirements increase
Solution Approach 1:
Segmenting information into dispersed sub-blocks allows the system to handle higher aggregate traffic by distributing power and bandwidth requirements across multiple smaller transmissions rather than requiring high peak power for single high-rate transmissions.
Solution Approach 2:
By dispersing sub-blocks across multiple time periods, the system converts continuous high-power requirements into periodic lower-power transmissions, reducing peak power demands while maintaining overall channel capacity through time-division multiplexing of the segmented data.
