... correspond to an empty TD. In order to exploit the results of Section 6.1, the stochastic network topology of the PPP needs to be mapped into a deterministic one with equally spaced nodes. In order to ... knowledge of p eq rtx (i), by using Equations (15) into (7) and (9), it is possible to obtain, respectively, D(i) eq (i = 1, . . . , N int ) and n hop rtx eq . Then, it is po...

... both in-band and out-of-band. In-band distortion results in an error per- formance degradation, while out-of-band radiation reduces spectral efficiency. Filtering methods can reduce out-of-band radiation, ... both QPSK and 16-QAM cases is derived.
