Design of Dynamic Wavelet Packet Division Multiplexing

Muscle Strength Weighting Based on Deep Learning and Wavelet Packet and Muscle Fatigue Analysis Based on L-Z Complexity

“…e established symbol sequence is S. is method is not sensitive to noise in dynamic structure analysis because only two states greater than the average value and less than or equal to the average value are considered. And it can only reflect the overall characteristics of the sequence, not the local characteristics [16].…”

“…According to the Lempel-Ziv complexity algorithm, it can be seen that the greater the complexity of a symbol sequence, the more operations it adds, the more new patterns it has, the more number of the least mutually different "substrings" required to describe a given symbol sequence, the weaker the periodicity of a given symbol sequence, and the faster the rate of new patterns. Conversely, the more repeated operations, the fewer the new patterns, the stronger the periodicity, and the slower the rate of new patterns appearing [16].…”

Design of MultiChannel Parallel Dynamic Testing Virtual Instrument Based on Dynamic Measurement

“…Traditional data acquisition equipment has limited functions, high upgrade and maintenance costs, complicated connection lines, and other drawbacks that make it impossible to meet today's data acquisition and processing needs. More and more users are eager to build a data acquisition and processing system on the virtual instrument platform in order to solve this set of problems [4,5]. e dynamic measurement method is used to monitor the machine's parameter change during operation, and signal analysis and processing technology is used to extract the characteristic information of the system parameter change from the vibration and noise in order to judge the nature of dynamic data, monitor, predict, and diagnose the working process and the state of the system in order to achieve the goal of preventing failure [6].…”
