In this video, part of our Whiteboard Video Series, Tristan Martin (Nutaq FAE) introduces us to the Quadrature Amplitude Modulation QAM and its impact on SDR transmission systems.

Points covered in this video include:

  • Relationship between BER (bit error rate), SNR (signal to noise ratio) and QAM levels for SDR transmission systems.
  • Difference between various M-QAM solutions and their impact on data rate.
  • Brief introduction to how Nutaq’s Radio420X solution, with its superior SNR performance, allows us to present a QAM64 OFDM reference design on our PicoSDR platform.
