New Bayesian Deep Learning Framework Tracks Hardware Impairments in MIMO Receivers

By PulseAugur Editorial · [1 sources] ·

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

IMPACT This research could lead to more robust and accurate channel estimation in wireless communication systems, potentially improving data transmission reliability.

    Message Passing Based Two-Timescale Bayesian Learning for Joint Channel and Memory Hardware Impairments Tracking

    arXiv:2607.01660v1 Announce Type: new Abstract: Hardware impairments in massive multiple-input multiple-output (MIMO) receivers introduce inter-symbol memory and inter-element coupling, severely degrading channel estimation. This paper employs a residual recurrent gated unit (RGR…
