A multi-standard and multi-antenna receiver is firstly designed with the ADS© software. Secondly, the performance of this system is evaluated with several multi-antenna algorithms, under real radio propagation conditions depending on the standard we choose to deal with. At this time the receiver can run with 802.11b and 802.11g standards in a 36 MHz bandwidth. Some first results are presented using multi antenna algorithm in a receiver dealing with two 802.11g or 802.11b transmission on overlapped communication channels.

We show that the combination of MIMO and multi-mode provides a solution to reduce global energy consumption, but that conclusions are really scenario-dependent. Moreover, we explain how a multi-mode MIMO terminal can improve these results using adaptive strategies.
