Smart Antenna System for 802.11A Applications
Tech ID: 21068 / UC Case 2004-191-0
Technology Description
Given here is an innovative multiple sub-carrier selection diversity receiver architecture for WLAN OFDM systems with multiple antennas. With a small increase in analog complexity, it is shown that significant gain can be achieved by the proposed technique over selection diversity for WLAN OFDM systems. The technique requires only a single A/D and DFT, which eases the baseband hardware requirements significantly.Applications
The invention will find applications in RF receiver design for WLAN OFDM systems with multiple antennas. It is also anticipated to be a good candidate for OFDM systems using a more complex frequency-domain combining. For example, in a system with four receiver antennas, MSCS combining can be employed to yield two outputs with an optimized SNR for subsequent maximal ration combining, thereby requiring only two complex A/D and DFTs.Related Materials
