Abstract :
In multiple-input multiple-output orthogonal frequency division multiplexing (MIMO/OFDM) systems, large complexity is considerable work. To mitigate this problem, high time resolution carrier interferometry (HTRCI) for MIMO/OFDM applying QR decomposition with M algorithm maximum likelihood detection (QRM-MLD) and channel ranking has been proposed. In the fast fading environment, since many errors are occurred in the last part of the packet, the decision direct method has been proposed. However, it requires also large complexity. Therefore, in this paper, we propose the non-linear prediction method for a HTRCI-MIMO/OFDM with QRM-MLD and channel ranking.
