Scalable OFDMA Physical Layer in IEEE 802.16 WirelessMAN
Hassan Yaghoobi, Intel Communications Group, Intel Corporation Index words: OFDMA, Scalable, IEEE 802.16, WirelessMAN, subchannel, subcarrier ABSTRACT
The concept of scalability was introduced to the IEEE 802.16 WirelessMAN Orthogonal Frequency Division Multiplexing Access (OFDMA) mode by the 802.16 Task Group e (TGe). A scalable physical layer enables standard-based solutions to deliver optimum performance in channel bandwidths ranging from 1.25 MHz to 20 MHz with fixed subcarrier spacing for both fixed and portable/mobile usage models, while keeping the product cost low. The architecture is based on a scalable subchannelization structure with variable Fast Fourier Transform (FFT) s
