Published in 2013 Proceedings of the 21st European Signal Processing Conference (EUSIPCO 2013), Marrakech, Morocco, pp. 1–5, 2013
This paper addresses the limitations of the Selective Spanning Fast Enumeration (SSFE) algorithm in detecting high-order modulation schemes in MIMO-OFDM systems. The authors propose Bounded Selective Spanning with Extended Fast Enumeration (BSS-EFE), an enhancement that improves detection performance and reduces computational complexity.
Key contributions include:
Algorithm Enhancement: Introduction of BSS-EFE to overcome SSFE’s limitations in spanning modulation schemes of 16-QAM or higher.
Performance Improvement: Achieving up to a 1 dB Bit Error Rate (BER) gain compared to SSFE.
Efficiency Gains: Reducing computational complexity by up to 16.3%, making the approach more suitable for real-time implementations.
Experimental Validation: Demonstration of the proposed method’s effectiveness through FPGA-based detectors for 2×2 and 4×4 16-QAM 802.11n MIMO systems.
