UWB Packet Segmentation with Variable PRF for Discontinuous Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultra-wideband (UWB) communication systems face challenges in efficiently transmitting packets at variable pulse repetition frequencies (PRF), particularly in maintaining performance while allowing for discontinuous packet transmission, which is desirable for implementation simplicity and power management.
Innovation Solution
A method and apparatus for transmitting packets in a wireless communication system by configuring the transmitter to send the first and second portions of a packet at different selected PRFs, enabling dis-continuous packet transmission, while maintaining performance comparable to prior art techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous packet transmission is used to maintain performance, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies periodic action by transmitting packets discontinuously with variable pulse repetition frequencies instead of continuous transmission. The system selectively transmits packets only when necessary, with configurable PRF values that allow for periodic transmission intervals, thereby reducing power consumption while maintaining acceptable transmission performance through strategic packet scheduling
2Ease of operation
If variable PRF transmission is implemented to reduce power consumption, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the pulse repetition frequency variable and configurable rather than fixed. The transmitter can dynamically adjust PRF values based on transmission requirements, allowing optimization of power consumption and performance through adaptive frequency selection while maintaining operational flexibility
3Ease of manufacture
If discontinuous packet transmission is used to simplify implementation, then ease of manufacture is improved, but transmission performance deteriorates
Solution Approach 1:
The patent applies parameter changes by varying the pulse repetition frequency parameter across different packet transmissions. By adjusting the PRF parameter, the system can optimize transmission performance for discontinuous packet scenarios, compensating for the potential performance degradation from non-continuous transmission while keeping the implementation relatively simple
