Abstract

This paper introduces the subband method of performing adaptive identification and analytic inversion of broadband MIMO channels. It shows that the techniques can potentially lower the computational cost while improving the performance for highly frequency-selective channelwith a long impulse response. It covers subband adaptive identification and shows two methods to invert a broadbandMIMO channel, the time-domain and frequency-domain methods. Finally results are shown for adaptationMSE, channel-equaliser MSE and BER performance.
