How do you compensate the Doppler effect?
In order to compensate for the Doppler shift during an approach toward an object of interest, the bat will lower the frequency of the calls it produces. The overall effect is that the echo frequency maintains nearly constant, and remains steadily within the auditory fovea.
How can you compensate for the impact of the Doppler effect in a cellular system?
A technique is described for compensating for that Doppler effect by using estimated bit decisions for received bits which are sufficiently close to a zero phase offset point so as not to have been corrupted by the Doppler effect.
What is Doppler in wireless communication?
Doppler effect is a fundamental phenomenon that appears in wave propagation, where a moving observer experiences dilation or contraction of wavelength of a wave.
What is Doppler shift compensation in echolocation in bats?
Doppler-shift compensation (DSC) is a highly specialized vocal behavior exhibited by selected groups of bats that rely upon a very narrowly tuned auditory system to discriminate fine acoustic details of their prey and to navigate through dense foliage (Schnitzler, 1967; Simmons, 1974; Simmons et al. 1979).
