Abstract

In this paper, we propose a new transceiver architecture for multiple-input multiple-output (MIMO) systems. The proposed scheme borrows ideas from the multilayered space-time coding (MLSTC) and threaded space-time coding (TSTC) schemes in an effort to maximize the diversity order while maintaining a low complexity detection. Specifically, the proposed scheme has a structure similar to that of the MLSTC while it employs a spatial interleaver (SI) in front of the MLSTC encoder. We also consider a low-complexity decoder that is based on the minimum mean squared error (MMSE) criterion and the QR decomposition (QRD). We provide analytical and simulation results through which we demonstrate that the proposed scheme provides improved diversity-multiplexing gain trade-off, as well as improved performance, all relative to the MLSTC scheme. In addition, with the proposed scheme, all layers achieve the same performance, which makes it attractive in multiuser environments.
