Simulated Bifurcation Algorithm for MIMO Detection

Abstract: We study the performance of the simulated bifurcation (SB) algorithm for signal detection in multiple-input multiple-output (MIMO) system, a problem of key interest in modern wireless communication systems. Our results show that SB algorithm can achieve significant performance improvement over the widely used linear minimum-mean square error decoder in terms of the bit error rate versus the signal-to-noise ratio, as well as performance improvement over the coherent Ising machine based MIMO detection method.
