Stein Variational Gradient Descent-Based Detection for Random Access with Preambles in MTC
ICASSP 2024accepted
Traditional preamble detection algorithms have low accuracy in the grant-based random access scheme in massive machine-type communication (mMTC). We present a novel preamble detection algorithm based on Stein variational gradient descent (SVGD) at the second step of the random access procedure. It e…
