Abstract: Disclosed are devices, systems, apparatuses, methods, products, and other implementations of GNSS repeater systems and methods for improving phase and frequency alignment of RF signals transported through fiber optic communication channels. Acquired RF signals are processed at a remote outdoor unit, where they are digitized, formatted into a CPRI frame, and timestamped. The timestamped CPRI frame is then transported over a fiber optic communication channel to an indoor head end unit. The indoor head end unit extracts timestamp and digitized RF signal from the CPRI frame. The timestamp is then used to synchronize a base transceiver station (BTS) and a precision time protocol (PTP) grand master with the remote outdoor unit.

Abstract: This disclosure relates to receiving an electromagnetic signal by a power detector, converting the received electromagnetic signal into a plurality of digitized samples, continuously acquiring and storing the plurality of digitized samples of into one or more sample memory buffers based upon a plurality of power processing events, simultaneously reading out of the one or more sample memory buffers the stored plurality of digitized samples, linearizing the plurality of digitized samples, wherein linearizing comprises converting the plurality of digitized samples into a plurality of linear power units such that the linear power units represent power measurements based upon the plurality of power processing events, and trace averaging the plurality of linear power units, wherein the simultaneously reading out of the one or more sample memory buffers, linearizing, and trace averaging are pipeline processed.
