Abstract

We extend the area property to more general linear channel models (including inter-symbol-interference (ISI) and multiple-input multiple-output (MIMO) systems) with arbitrary input constellations. We show that the theoretical limit of a channel (i.e., the mutual information) can be achieved under some assumptions. Several engineering techniques are examined to ensure these assumptions. It is shown that the required assumptions can be approximately materialized using superposition coded modulation (SCM) and a precoding technique.
