Abstract
To support broadband multiple-input multiple-output (MIMO) systems using a single carrier transmission scheme under frequency selective fading conditions, this paper proposes a new space-time turbo equalization scheme that employs beam steering technique based on singular value decomposition (SVD) and QR decomposition (QRD) are employed to suppress mutual interference between eigen-beams called inter-beam interference (IBI). In addition, soft interference cancellation followed by minimum mean square error filtering (SC/NMSE) type turbo equalizer is applied to each eigen-beam signal sequence to suppress co-beam interference (CBI) defined as inter-symbol interference (ISI) on the co-eigen-beam, as well as the residual IBI. Computer simulation confirms that the proposed scheme is effective in improving spectral efficiency without extra bandwidth with low transmit power.
