... fashion. The problem of throughput capacity of ad hoc wire- less networks has received a lot of attention starting with the article [1] in which it was shown that the throughput of random networks ... total transport capacity of the network is up- per bounded as C T ≤ c 3 (α)W  P N 0 W  ρ α/2  An (51) with high probability. Proof. Since the “quantum” C T,ij of the transpo...

... example, we see that the worst case PAPR behavior of an OFDM signal is just an instance of the √ N behavior of any N orthonormal signals [16]. A theorem of Kashin and Tzafriri [21]statesthat under ... size of a subset of transmission signals and several signal processing properties of the subset. In Section 2, we prove our main result on tone reservation for OFDM systems with a...
