摘要：
The joint channel estimation and data detection problem for Multi Input Multi Output Single Carrier Cyclic Prefix (MIMO SCCP) systems is considered in this paper. The detection process is completed by Block Iterative generalized decision feed back equalizer (BI GDFE) method. The BI GDFE method provides the soft information of the transmitted signals to the Expectation Maximization (EM) based channel estimation. The Cramer Rao Lower Bound (CRLB) is also derived to evaluate the quality of estimated parameters. Simulations show that the proposed iterative structure has the bir error rate (BER) performance close to the that of the BI GDFE method with perfect channel state information (CSI).
