Gaussian Pulse Based Tone Reservation for Reducing PAPR of OFDM Signals
Abstract – One of the major drawbacks of OFDM is high Peakto-Average Power Ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplif...

A Lower Bound for Agnostically Learning Disjunctions
We prove that the concept class of disjunctions cannot be pointwise approximated by linear combinations of any small set of arbitrary real-valued functions. That is, suppose there ...
