Signal

Tapers start and end samples of a given signal for a fade-in and fade-out effect. Fade-in and fade-out durations can be independently controlled. Custom tapering window can be specified also.

the m-file helps you o understand the generatio,transmission and reception of an ofdm signal, and also shows the effect of the channel noise and the HPA on the ofdm signal.

This function Calculates Power Spectral Density of signal vector X using Welch's averaged periodogram method.X is divided into sections, then windowed by the WINDOW parameter.The magnitude squared of the length NFFT DFTs of the sections are averaged to form Pxx. Pxx is length NFFT/2+1 for NFFT...
