Crámer-Rao Bound Analysis for Mixed-ADC Direction of Arrival Estimation in Two-Dimensional Arrays

Abstract: Digital modulation schemes, such as phase-modulated continuous wave (PMCW) and orthogonal frequency-division multiplexing (OFDM), require high-sampling analog to-digital converters (ADCs), ...
