Abstract :
A dual mode 2times2 MIMO OFDM & OFDMA receiver is implemented with shared hardware resources. This dual mode receiver functions well in both static and mobile channels. It follows the specification requirement of EWC HT PHY V1.27 and IEEE 802.16e-2005, and proposes a PHY baseband simulation model to meet the specifications. Additionally, equalization supports both static and dynamic channel estimation. 2times2 MIMO STBC and V-BLAST are supported as well. A low cost ICI (inter-carrier interference) cancellation hardware is also proposed.
