Abstract :
In this paper, the performance limits and computational complexity of lattice sequential decoder for coded MIMO channel are analyzed. It is shown that using nested lattice codes, the optimal diversity-multiplexing tradeoff of the channel can be achieved in the presence of such very low complexity decoder. We show that the computational complexity distribution, at high signal-to-noise ratio, is dominated by the outage probability.
