Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

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 ...

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 ...

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 ...
