On encoding and rate adaptation for MIMO_NC

MIMO_NC is a recently proposed physical layer technique that combines MIMO signal processing and Network Coding. However, it has also been shown that the diversity offered by MIMO_NC cannot be greater than what standard NC offers. In this paper we propose a new encoding strategy for MIMO_NC that improves the diversity order and a rate adaptation technique tailored on MIMO_NC that offers diversity and coding gain over conventional NC.
