Solution Overview
Problem
Portable communication devices face power consumption challenges due to continuous transmitter operation, which limits their usage time, especially when power sources are limited.
Innovation Solution
A method involving the transmission of signals using bursts of pulses during a first portion of a transmission frame, with silence or a distinct signal during the second portion, allowing for power conservation and efficient data extraction by receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmitter is operated continuously to ensure reliable signal transmission, then communication reliability is improved, but power consumption increases and continuous use lifetime decreases
Solution Approach 1:
The transmitter operates in periodic bursts rather than continuously. Each transmission frame contains active portions with pulse signals and inactive silence portions where the transmitter is off. This periodic operation reduces average power consumption while maintaining communication reliability through proper frame结构设计 that includes synchronization and data portions.
Solution Approach 2:
The transmitter dynamically switches between active and inactive states based on whether data needs to be transmitted. The system adapts its operation mode (transmitting or silent) according to communication requirements, optimizing the balance between reliability and power consumption rather than operating in a fixed continuous mode.
2Reliability
If the transmitter is operated continuously, then signal transmission is maintained, but power consumption increases
Solution Approach 1:
The transmitter uses periodic burst transmission with silent intervals between frames. During silence portions, the transmitter consumes minimal power. This periodic operation maintains signal transmission capability while significantly reducing average power consumption compared to continuous operation.
Solution Approach 2:
The transmission is segmented into discrete frames, each containing synchronization portions and data portions. The transmitter only activates during these segmented transmission intervals rather than operating continuously, reducing overall power consumption while maintaining reliable signal delivery when needed.
3Use of energy by moving object
If pulse-based modulation is used to reduce power consumption, then power efficiency is improved, but the complexity of frame detection increases for receivers
Solution Approach 1:
The synchronization portion of each frame is designed with distinctive pulse patterns that precede the data portion. This preliminary synchronization signal prepares the receiver by providing a known reference pattern that simplifies subsequent frame detection and data extraction, reducing the complexity burden despite using pulse-based modulation.
Solution Approach 2:
The system uses distinct pulse parameters (such as pulse width, repetition frequency, or amplitude) in the synchronization portion compared to the data portion. These parameter changes create detectable differences that help receivers identify frame boundaries and distinguish synchronization from data, simplifying detection despite the pulse-based modulation scheme.
Data Source
AI summary
A method of transmitting and receiving data frames using pulses is disclosed. According to the transmitting method, a first signal is transmitted including one or more bursts of pulses during a first portion of a transmission frame, and not transmitting the first signal during a second portion of the transmission frame. The not transmitting the first signal may include maintaining one or more silence periods for the second portion of the transmission frame, or transmitting a second signal distinct from the first signal. According to the receiving method, a signal including one or more bursts of pulses is received during a first portion of a transmission frame, an analysis of the one or more bursts of pulses is performed, and the transmission frame is detected based on the analysis of the one or more bursts of pulses.
