Abstract
To reduce an adjacent channel interference (ACI) by sharpening the spectrum edges of the orthogonal frequency division multiplexing (OFDM) signal in the frequency domain, an windowing function is applied to the individual OFDM symbols in time domain. A commonly used windowing function is the raised cosine function with a roll-off factor. In this paper, the spectrum of an OFDM signal and -45 dB bandwidth have been investigated with respect to various roll-off factors used in the data-over-cable-service-interface-specifications (DOCSIS) 3.1 using OFDM.
