Project Description

Course Overview

This short online course describes and explains key digital modulation measurements made on modern RF and wireless transmitters and receivers. Transmitter measurements covered include two-tone intermodulation, adjacent channel power (ACP), harmonic and spurious signals as well as different types of error vector magnitude. This is followed by receiver measurements, with a particular emphasis on handset measurements such as bit error rate (BER), receiver sensitivity and spurious response measurements.
