New modulation schemes don’t come along very often. In fact, it has been years…decades really…. since any new modulation method has been invented. Remember there are only three basic ways a carrier ...

Rohde & Schwarz, in collaboration with Broadcom, will display its CMX500 multi-technology multi-channel signaling tester at Mobile World Congress (MWC) Barcelona 2026 with newly added Wi-Fi 8 (IEEE ...

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

Software-defined radio is transforming test and measurement by replacing rigid hardware with adaptable software, enabling ...

As our society’s hunger for data grows—not only more data, but more data delivered faster—older modulation schemes based on NRZ-type encoding grow increasingly inadequate. We need to get data from ...

Error vector magnitude (EVM) is a measure of modulation quality and error performance in complex wireless systems. It provides a method to evaluate the performance of ...
