Abstract-- In this paper, we derive an analytical expression
for the exact pairwise error probability (PEP) of a space-time
coded system operating over a spatially correlated slow fading
channel using a moment-generating function-based approach.
This analytical PEP expression is more realistic than previously
published exact-PEP expressions as it fully accounts for antenna
spacing, antenna geometries (Uniform Linear Array, Uniform
Grid Array, Uniform Circular Array, etc.) and scattering models
(Uniform, Gaussian, Laplacian, Von-mises, etc). Inclusion of
spatial information provides valuable insights into the physical
factors determining the performance of a space-time code. We
demonstrate the strength of our new analytical PEP expression
