User Ordering and Subchannel Selection for Power Minimization in MIMO Broadcast Channels using BD-GMD


This paper studies the power minimization problem for the MIMO broadcast channel. The optimal solution involves interference-balancing (IB) and iterative convex optimization procedures. In this paper, the zero-forcing (ZF) problem is considered, with dirty paper coding (DPC), resulting in a simple non-iterative implementation using the block diagonal… (More)
