Abstract: This letter considers two-dimensional direction of arrival (DOA) estimation of coherent signals exploiting a moving uniform rectangular array. The motion of the array induces phase ...

ABSTRACT: A new nano-based architectural design of multiple-stream convolutional homeomorphic error-control coding will be conducted, and a corresponding hierarchical implementation of important class ...

May 30 (UPI) --A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique - the etchings, lines like tally marks, may have ...
