... s 1 (t)forallt where |s(t)|≤M.Then,s − s 1 has compact support and cannot be band-limited. Since s is band-limited, this means s 1 cannot be band-limited, and thus out-of-band radiation has been caused. This motivates ... sets remains fixed for all codewords and over all uses of the channel. Of the handful of methods to reduce PAPR, tone reser- vation is particularly robust and canon...
