In this paper, we present a 2x-site test solution for GSM transceivers using only baseband signals for analysis. We perform all operations on standard-compliant GSM packets, thereby putting the device under the normal operating conditions. The transmitter on one device under test (DUT) is coupled with a receiver on another DUT to form a complete Tx-Rx path. Parameters of the two devices are decoupled from one another by carefully modeling the system into a known format and using signal processing techniques. Simulation as well as measurement results confirm the high accuracy of the proposed technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
