چکیده
The frequency-domain received single-carrier (SC) signal can be expressed using the matrix representation similar to the multiple-input multiple-output (MIMO) multiplexing. The signal detection schemes developed for MIMO multiplexing can be applied to the SC transmissions. In this paper, we apply maximum likelihood detection employing QR decomposition and M-algorithm (QRM-MLD) to the SC signal detection with antenna diversity reception. We show that by using antenna diversity reception, the number of surviving symbol candidates can be reduced. We evaluate, by the computer simulation, the bit error rate (BER) performance achievable by QRM-MLD and compare it with that achievable by the Vertical-Bell Laboratories Layered spacetime architecture (V-BLAST) detection.

Abstract—QR decomposition and M-algorithm based near maximum likelihood detection (QRM-MLD) is a promising detection scheme for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM).
