Soft-input-soft-output (SISO) MIMO detection is implemented with a lattice reduction aided (LRA) K-best searcher and a max-log list demapper. A hardware-efficient IDD receiver is proposed to achieve the required packet-rate (PER) with a feasible latency. The extrinsic information transfer (EXIT) chart is utilized to reduce the number of iterations for IDD. Given the 802.11ax latency constraint, the performance, power, area (PPA) design space is explored to identify the optimal IDD receiver architecture. 50% of IDD inner iterations are reduced with only a 0.05dB loss in PER. The proposed IDD receiver achieves a 1dB improvement in PER with 3.6\times smaller area and 3.0 \times lower power consumption when compared to the best non-IDD receiver. ? 2020 IEEE. |
