The use of multiple antennas at both the transmitter and receiver is well motivated by the substantial performance gains that can be realized, both in terms of an increase in achievable data rate and a decrease in error rate. The achievable data rate is characterized by the mutual information of the channel. In case of frequency selective Multiple Input Multiple Output (MIMO) channels, expressions for mutual information are obtained by using a block transmission model. In this paper, the authors consider a filterbank equalization framework, which is an attractive alternative to the block processing approach.
