Blind Equalization Based on Proximal Alternating Optimization
Wonseok Kang, Minsik Kim, Daeyoung Park · 한국통신학회논문지 · 2023
In this letter, we consider a joint channel estimation and signal detection algorithm for blind equalization in short-packet communications. We divide the non-convex blind equalization problem into two sub-problems and propose a channel estimation and signal detection algorithm based on the proximal alternating optimization. Experimental results show that the proposed algorithm provides the bit error rate (BER) performance improvement over existing methods.
