We give a performance analysis for space-time trellis codes under correlated fading channels, and propose a new code design criterion that takes into account channel correlation. A simple form for a distance metric that characterizes the code performance in presence of transmit correlation is also given. We further show how recent constellation rotation techniques may not be sufficient to ensure improved performance of the code under correlated channels.

Abstract
We give a performance analysis for space-time trellis codes under correlated fading channels, and propose a new code design criterion that takes into account channel correlation. A simple form for a distance metric that characterizes the code performance in presence of transmit correlation is also given. We further show how recent constellation rotation techniques may not be sufficient to ensure improved performance of the code under correlated channels.File in questo prodotto:
