In THz communication systems, performance evaluation is essential for transceivers that support wideband signals and higher-order modulation schemes. However, when the expected communication performance cannot be achieved, identifying the underlying cause is often challenging because performance degradation may originate from multiple factors, including the transceiver, frequency conversion stages, and transmission path.
This white paper reviews the key performance metrics used to evaluate THz communication transceivers and explains the insights that can be obtained from measurements of Error Vector Magnitude (EVM), phase noise, frequency response, and S-parameters. It also introduces an effective approach for identifying performance degradation factors, along with key considerations during the design and evaluation process.
