摘要

A basic challenge for future wireless communication systems is the contradiction between the fast growing demand for high speed wireless communications and the limited electromagnetic wave frequency spectrum. The multiple-input multiple-output (MIMO) technique with space-time coding (STC) is recognized as a promising scheme for the next-generation of high speed wireless communication systems. This is mainly because of its capability of providing spatial diversity to combat fading in wireless channels and increasing the capacity without
