Technology 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.

Detailed 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.
