Abstract:

In the usual application of Multiple-Input, Multiple-Output (MIMO) and space–time coding (STC) the basis of the operation is a rich-scattering fading channel and a high density of links. In this paper a different situation: cellular millimeter-wave systems are investigated. It is shown that the MIMO concept can also have advantages in this case. Rain-induced fading characteristics and the concept of route diversity are briefly introduced. A route diversity system can be regarded as a parallel MIMO channel. Basic characteristics of these channels including capacity for various cases are investigated. Optimal codes are determined for space-time convolutional coding. Conceptual design of a route-time coding (RTC) system is shown. Simulation results on coding gain, based on empirical rain attenuation data are given.

Keywords: Route diversity; MIMO channels; route-time coding; parallel MIMO channels
