Explore the effect of MIMO integration in WiMAX systems: EDA software and the Mobile WiMAX Wireless Library help MIMO/WiMAX designers meet performance specifications.(multiple-input multiple-output )

Wireless Design & Development, January, 2007 by Xu, Jinbiao; Amini, Afshin

The IEEE 802.16e-2005 Wireless Metropolitan Area Network (MAN) orthogonal frequency division multiple access (OFDMA) mode (mobile WiMAX) is based on the concept of scalable OFDMA (S-OFDMA). S-OFDMA supports a wide range of bandwidth set to flexibly address the need for various spectrum allocation and usage model requirements.

Moreover, the Mobile WiMAX specification defines multiple-input multiple-output (MIMO) option, which is a key feature in mobile WiMAX. Smart antenna technologies typically involve complex vector or matrix operations on signals due to multiple antennas. OFDMA allows smart antenna operations to be performed on vector-flat sub-carriers. Complex equalizers are not required to compensate for frequency selective fading. OFDMA therefore, is...
