Biconvex ADMM for Sensing-Aided XL-MIMO Channel Estimation at the THz Frequency Band

Evangelos Vlachos and George C. Alexandropoulos

Terahertz XL-MIMO links suffer from dual-wideband fading, where beam squint and multipath delay spread couple angle and delay estimation across hundreds of antenna pairs. The paper uses the base station’s monostatic radar output to warm-start an ADMM estimator that jointly recovers the channel and its binary delay support, at no extra pilot cost, and closely approaches the Cramér-Rao Bound.
