摘要：

This paper extends the traditional Clarke/Jakes model for a frequency flat fading process in a land mobile radio system to facilitate the examination of coherent space-time demodulation systems, The work develops a space-time correlation function using a ring of scatterers model around the mobile unit. The resulting correlation function permits the investigation of a variety of issues concerning base station configurations in space-time systems. The interrelationship of the fading process between the space and the time domain is explored. A detailed example regarding the effects of antenna separation in a receiver diversity system is considered. A set of design rules for interleaving depth and antenna separation in a space-time modem is presented and quantified.
