Direct Complex Envelope Sampling of Bandpass Signals With M-Channel Time-Interleaved ADCs

IEEE Transactions on Signal Processing, 2022
Classical receiver architectures demodulate a bandpass signal to baseband before sampling the in-phase and quadrature components. With the advent of faster analog-to-digital converters (ADCs) and wide bandwidth sample and hold (S/H) circuits, it has ...
