Novel Preamble-Based Channel Estimation for OFDM/OQAM Systems
OFDM/OQAM has been considered as an attractive alternative to classic OFDM with cyclic prefix (CP) over doubly dispersive channels. By utilising well designed pulse shapes and remo...

Selectivity-based partitioning: a divide-and-union paradigm for effective query optimization
Modern query optimizers select an efficient join ordering for a physical execution plan based essentially on the average join selectivity factors among the referenced tables. In ...
