receiving-diversity bound spatially multiplexed systems multiple-input-multiple-output(MIMO)single carrier-frequency-domain equalization(SC-FDE) iterative detection algorithm
To improve the detection reliability and reduce the computational complexity of multiple-input-multiple-output(MIMO)single carrier-frequency-domain equalization(SC-FDE)systems, a novel iterative signal detection algorithm, called iterative interference cancellation(IIC), is proposed. Moreover, a receive diversity lower bound(RDLB)is derived as a benchmark to evaluate the bit error rate performance. The proposed IIC utilizes the initial value provided by the basic linear equalization algorithm, progressively removes the inter-layer interference by the iterative process, and gradually improves the reliability of the detected results. The results indicate that the proposed IIC approaches to the RDLB at the Eb/N0 of 9 dB and 16 dB for 4-ary and 16-ary quadrature amplitude modulations, respectively. The computational complexity of an iterative loop is linear to the number of transmit antennas, and the overall complexity is lower than that of a popular vertically Bell laboratory layered space-time detector when the antenna size is larger than 3×3. Therefore, the proposed algorithm remarkably enhances the reliability of MIMO SC-FDE systems with an antenna size of not less than 3×3 and is computationally efficient and practical even in large-dimension MIMO systems for 5th-generation(5G)or beyond 5G communications.
