In this second part, we tackle the "detection problem," which consists of determining the number of targets. First, the target parameters are estimated, assuming a maximum number of possible targets.

Abstract: A 112-Gb/s mixed-signal 4-level pulse amplitude modulation (PAM-4) receiver (RX) with clock-data recovery (CDR) for extra-short-reach (XSR) applications is presented. An ultra-fine ...
