IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC) : Montreal, CANADA : OCT 08-13, 2017. Multiuser (MU)-multiple-input multiple-output (MIMO) receivers often need to take iterative strategies to cancel multiuser-interference (MUI). Frequency domain turbo equalization is one of the most promising solutions to the MUI problem. It offers a reasonable trade-off between the receiver performance and the computational complexity by assuming cyclic prefix (CP)-transmission. Nevertheless, CP-transmission is not preferable for the battery life of user terminals. Therefore, this paper proposes a new frequency domain multiuser-detection (MUD) technique by extending the chained turbo equalization (CHATUE) to MU-MIMO systems. Simulation results verify that the proposed MU-MIMO CHATUE algorithm is a more reliable option to improve the spectral-and/or energy-efficiency by eliminating the necessity of CP-transmission than by shortening the training sequences or puncturing the coded data bits.
