Abstract: In order to solve the problems of signal attenuation and low transmission efficiency in low-orbit satellite data transmission, this paper analyzes and implements an effective modulation and ...

ABSTRACT: To overcome the problem of calculation errors in the Born approximation when the forward accumulation effect is strong in VTI media, this article combines the De Wolf approximation method ...

Abstract: This paper deals with discrete Fourier transform (DFT)-based modulation and demodulation techniques for affine frequency division multiplexing (AFDM), as opposed to using the discrete affine ...
