In this paper, we investigate the impacts of transmitter and receiver windows on performance orthogonal time-frequency space (OTFS) modulation propose window designs to improve OTFS channel estimation data detection performance. particular, assuming ideal pulse shaping filters at transceiver, derive windowing effective its in delay-Doppler (DD) domain, total average transmit power, noise covari...

In order to improve the time-frequency resolutions of short-time fractional Fourier transform, adaptive short-time fractional Fourier transform (ASTFRFT) method is used in this paper. The optimal order of ASTFRFT is given by maximizing kurtosis of signals in fractional domain, where the window width of ASTFRFT is searched by the maximal Shannon entropy of timefrequency distribution. Short-time ...

This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...
