Link Abstraction for Multi-User MIMO in LTE Using Interference-Aware Receiver

Free registration required

Executive Summary

Most of the recent wireless communication systems are interference limited rather than noise limited. In the case of a very strong interferer the conventional assumption of the interference as Gaussian is extremely suboptimal. However, optimal (capacity achieving) receivers utilize some prior knowledge about the interference to reach optimality. The link abstraction for such receiver structures is not studied well. The authors investigate how the conventional mutual information based link abstraction technique can be extended for the accurate and efficient link performance modeling for low complexity optimal receivers.
