The fundamental concept of the frequency coding
technique is to control the presence or absence of a resonance at particular frequencies of the spectrum.
Under the interference of background, research has shown that the time and frequency diversity of frequency hopping signal, if proper frequency coding
, can get good time delay and Doppler resolution features.
Utilizing an innovative system of "Time Frequency Coding
," ZeroWire Ultra units are programmed to change frequency bands in a specific sequence and timing, creating nine non-interfering channels.
Space B is made up of sequence which has the same frequency coding
table with coding sequence.
The topics include the physics of sound, the anatomy and physiology of the cochlea, the lateral lemniscus and inferior colliculus, perceptual correlates of frequency coding
in the auditory system, and intensity coding throughout the auditory system.
Furthermore, a CRB optimization proposal based on frequency coding
design is proposed, aiming to minimize the CRBs of the target's 3D parameters estimation.
