2. Orthogonal frequency division multiplexing (OFDM), where the signal is built in the frequency do- main and then a fast Fourier transform (FFT is taken to get samples of the time domain signal for transmission, is used in a large range of wireless communication standards such as 4G cellular. One drawback of OFDM is that the time domain samples can exhibit large peaks, hence making efficient amplification difficult. Motivated by the Central Limit Theorem (which we will learn later), the...
