New Bayesian Deep Learning Framework Tracks Hardware Impairments in MIMO Receivers

Researchers have developed a novel framework called MP-TTBDL, which utilizes message passing and Bayesian deep learning to jointly track channel and hardware impairments in massive MIMO receivers. This approach models the distinct timescales of wireless channels and hardware drift by assigning different Markov priors. The framework separates channel estimation and impairment calibration modules, iteratively exchanging information until convergence, and has demonstrated lower channel estimation error compared to conventional methods. AI
