TV White space (TVWS) is one of the candidates for future wireless communications. However, the criteria for multiple TVBDs are insufficient. Therefore we propose an optimization method for multiple TVBDs with multiple TVWS channels to minimize the i

Multiple TVBDs with different TVWS channel under Korean TVWS regulation in the same pixel can cause harmful interference to DTV receiver. To overcome this problem, we propose an optimization method for multiple TVBDs with multiple TVWS channels to mi

Repeaters equipped with on-board digital baseband processing in a time division duplex (TDD) demand short processing time in order to alleviate inter-symbol interference resulting from having a time delay that is greater than the guard time. To accom
