Survey of channel estimation method in delay-Doppler domain for OTFS
Published 2022-12-01“…In order to provide reliable communication service for high-mobility scenarios, 6G can consider DD (delay-Doppler) domain based OTFS (orthogonal time frequency space) as its modulation scheme.By mapping the transmitted symbols onto DD domain and transforming them into TF (time-frequency) domain, OTFS endows all the transmitted symbols with the potential of capturing time-frequency full diversity, effectively improving the performance of communication in time-varying fading channels.Due to the superior properties of DD effective channel, the existing OTFS channel estimation methods were mostly carried out in DD domain.Considering the difference of implementation and application scenarios, existing DD channel estimation methods for OTFS were divided into three categories and overviewed, after which the challenges and potential solutions for current DD channel estimation methods were summarized and analyzed.…”

Organizational Balance as a Key to Enterprise Reorganization
Published 2022-10-01“…According to the authors, the manager gets a chance to see their organization and conduct needed changes that do not contradict its ‘nature’ only with the help of the organizational balance notion. The method of restoring organizational balance proposed for carrying out transformations is built on the artificial abstract separation of activity (business) and organization, their separate examination and diagnostic with further analysis and assembling steps on balancing with proposals aimed at upgrading businessprocesses within the frames of complicated organizational concept.…”
