Performance Analysis of Space-Time CDMA Systems over MIMO Rayleigh Fading Channels
Dianjun Chen, Takeshi Hashimoto (Univ. of Electro-Comm.)
Abstract (in Japanese) (See Japanese page) 
(in English) For an AWGN channel,
indecomposable error vector (IEV) is introduced to tighten
the BER (bit error rate) upper bound of the optimum multiuser detector
[Verdu, 86].
For MIMO Rayleigh fading channels, IEVs determine a integral region
when error probability is averaged with respect to the given path coefficients.
In this paper, averaging the error probability
over the integral region determined by IEVs,
we calculate a BER upper bound for the ML receiver
in a downlink space-time CDMA system.
This upper bound is tighter than the bound proposed in [Chen and Hashimoto, 04].
