STBCs with optimal diversity-multiplexing tradeoff for 2, 3 and 4 transmit antennas

This paper shows that the codes from division algebras (Sethuraman et al., 2003) achieve the optimal diversity-multiplexing tradeoff for n transmit and n receive antennas for n=2,3,4 by simulation. It also present a lower bound for the tradeoff curve which shows that codes from division algebras for arbitrary number of transmit and receive antennas achieve points corresponding to zero diversity gain and zero multiplexing gain.
