Abstract"This paper presents a modification on the original space-time code scheme with the objective of improving its performance. Interleaving and rotation of the signal constellation, which do not affect the performance of the system for the additive white Gaussian noise channel, are introduced. The spectrum efficiency of the scheme is not altered and the modification of the modulator is very simple. Simulations are carried out to show that the error probability is improved, for the proposed scheme, in a fading environment."
