Upper and lower bounds on capacity of quantized MIMO ISAC are tight at low SNR, saturate at high SNR due to quantization, and i.i.d. Gaussian signaling is near-optimal; closed-form LMMSE also saturates under Kronecker model.

Fundamental Limits of Quantized MIMO ISAC under Gaussian Signaling
Upper and lower bounds on capacity of quantized MIMO ISAC are tight at low SNR, saturate at high SNR due to quantization, and i.i.d. Gaussian signaling is near-optimal; closed-form LMMSE also saturates under Kronecker model.
