摘要：
The number of wireless devices worldwide has increased exponentially over the past decade, inherently imposing consumer requirements for faster data rates and longer device life. Current wireless standards such as long-term evolution (LTE), worldwide interoperability for microwave access (WiMAX), and the family of IEEE 802.11a/g/n/ac/ad for home-networking use orthogonal frequency-division multiplexing (OFDM) as their basis for digital multicarrier modulation. An option for increasing OFDM data output is through the expansion of the constellation symbols or the number of data subcarriers © 2016 IEEE.
