Distributed MIMO Precoding Strategies in a Multicell Environment

摘要

We investigate distributed multiple-input multiple-output (MIMO) precoding schemes for coping with the intercell interference in a multicell environment. In particular, we introduce the effective channel matrix for two different precoding strategies, referred to as received interference-aware precoding (RIAP) and generated interference-aware precoding (GIAP). Then, we propose a hybrid precoding scheme and a switching scheme. Simulation results are provided to compare the performance in a multicell environment.
