Abstract	In this paper, considering a multiple-input multiple-output (MIMO) system, we expose an adaptive method for a nulling-and-cancelling detection scheme. The proposed method takes advantage of the temporal correlation of a Rayleigh fading MIMO channel in order to reduce the complexity of all the decoding steps. We especially focus on the decoding ordering, which is a crucial step in a zero forcing detection feedback equalizer (ZFDFE) decoding scheme. The corresponding columns permutation performed on the channel matrix is adaptively updated from the past channel information using an ad-hoc fixed parameter that offers a very good performance/complexity tradeoff.
