This paper introduces cross-correlation detection theory and maximum likelihood theory and based on the two theories, puts forward a new method for weak signal detection.
The dynamic digital display sphygmomanometer is designed by using the technology of weak signal detection.
Study of weak signal detection based on chaotic oscillator and wavelet theory
When exploring and researching on macroscopical and microcosmic world, the weak signal detection is needed.
Novel approach of real-time ELF weak signal detection based on least square algorithm
Signal detection system based on chaos theory has the critical sensitivity to periodic signal and the immunity to the strong noise, which can be used in weak signal detection area.
According to the different types of power supply, there are chaotic state weak signal detection circuit of constant-current and chaotic state weak signal detection circuit of constant-voltage.
