ABSTRACT:
A new frame structure applicable to the IEEE 802.16 OFDMA wireless waveform is described, for the purposes of increasing base station capacity, increasing subscriber link rates and extending base station range. The frame structure provides the necessary constructs so that advance signal processing technologies such as Stacked Carrier Spread Spectrum and adaptive antenna technology may be used in combination with these constructs in order to realize these gains. These concepts are equally applicable in other advanced wireless waveforms based on OFDM or OFDMA such as LTE or UMB.
