Abstract

In modern wireless communication, Multiple-Input Multiple-Output (MIMO) takes advantage of spatial diversity to increase the capacity and spectrum efficiency effectively. This technology, however, poses many technical challenges for device implementation. optimizing the computational workload with an acceptable bit error rate (BER) becomes the critical design problem for the MIMO relay station. This paper proposes a novel detection algorithm for the wireless MIMO in the two-way relay station (TWRS). We adopt the relay architecture that doubles the receive antennas for communication data between two MIMO terminals. The core processing block employs a variable K-Best detection (V-KBD). The simulation for $4\times 4$ MIMO two-way relay results shows that our relay model could achieve BER close to the conventional SD algorithm systems with fixed and lower complexity. © 2021 IEEE.
