Implement OFDMA, MIMO for WiMAX, LTE

Posted: 17 Mar 2008 ?? ?Print Version ?Bookmark and Share

Keywords:OFDMA? MIMO? wireless industry? WiMAX? LTE?

The wireless industry is in transition. All of the new 4G air-interfacesWiMAX, Long Term Evolution, Ultra Mobile Broadband, 802.20, Wireless Broadband, next-generation PHS and the likeshare some things in common: all are based on OFDM Access (OFDMA); all exploit MIMO; and all have "flattened architecture" and all are Internet Protocol-based.

This article discusses WiMAX and LTE: in particular, how to implement the core DSP algorithm of OFDMA, then the novel variant used by LTE for the uplink, and finally a brief discussion on MIMO for both WiMAX and LTE. It describes these in the context of a software-defined flexible architecture.
