Method for re-ordering multiple layers and detecting signal of which the layers have different modulation orders in multiple input multiple output antenna system and receiver using the same

摘要

Disclosed are a method for re-ordering multiple layers and detecting signals and a receiver using the same to be able to exert performance approaching a maximum likelihood scheme while having lower complexity than that of the maximum likelihood scheme in a multiple input multiple output (MIMO) antenna system in a form where each layer is modulated and transmitted with different modulation orders.
