Arrangements of Segments that Share Endpoints: Single Face Results
We provide new combinatorial bounds on the complexity of a face in an arrangement of segments in the plane. In particular, we show that the complexity of a single face in an arran...

An Adaptive-Scaling Tone Reservation Algorithm for PAR Reduction in OFDM Systems
— Existing tone-reservation algorithms (such as the controlled clipper algorithm) for OFDM require a number of iterations to ensure the reduction of Peak-to-Average Power Ratio (...
