Abstract
The generation of OFDM signals for DOCSIS 3.1 specification having a required number of subcarriers and subcarrier spacing can be based on a sampling rate that is modified from that defined by the DOCSIS 3.1 specification. In embodiments, the base sampling rate is defined as Fs=204.8*A MHz (A>1), with a respective increase of basic IFFT size by factor A. In embodiments, the OFDM signal is sampled at a sampling rate of 204.8 MHz*A for an IFFT size of 8192*A (4096*A), where A>1.
