Abstract

In multiple-input multiple-output (MIMO) communications systems, a crucial role is played by channel estimation as the accuracy of estimation will have a substantial effect on the overall system performance. In this paper we consider designing precoding matrices and blind channel estimation algorithms for MIMO single carrier with frequency domain equalization (MIMO-SC-FDE) systems. By deriving the relationship between the MIMO orthogonal frequency division multiplexing (MIMO-OFDM) and MIMO-SC-FDE, the theories for precoding and channel estimation for MIMO-OFDM can be directly used for MIMO-SC-FDE. Based on this, several new precoding matrices are designed and tested. The proposed precodings will not affect the power of the precoded block. Furthermore, fast algorithms are used for the implementation of the precoding and decoding.
