In this paper, a new two-dimensional (2D) time-frequency distribution is introduced by extending the 1D Lv distribution (LVD). The 2D LVD inherits the desirable properties from the 1D LVD so that it has advantages of high signal energy concentration and trivial cross-terms since it is based on coherent integration. Important performances of signal energy concentration and computational complexity...
This paper proposes an effective method, based on the concept of phase cancellation and filtering, to suppress interference containing multiple linear frequency modulated (LFM) sinusoidal components for direct sequence spread spectrum (DSSS) communications. Since the recently reported Lv distribution (LVD) provides a better concentration of signal energy in the domain of frequency and chirp rate,...
