A Primer on Quadrature Amplitude Modulation (QAM)

Quadrature Amplitude Modulation (QAM) is a spectrally efficient modulation scheme used in most of the high-speed wireless networks today. Just like Pulse Amplitude Modulation (PAM) transmits information through amplitude scaling of a pulse, QAM performs the same operation in two dimensions. Watch the video to explore how this is done. #wireless #modulation #communicationsystems #quadrature #digitalsignalprocessing #digitalsystemdesign Take the SDR course with GNU Radio exercises to send and receive your own wireless signals (text and image) over the air without expensive SDR hardware through a speaker (Tx) and a microphone (Rx). https://wirelesspi.com/sdr-course/ Learn about wireless communications, DSP and SDRs from my book Wireless Communications from the Ground Up - An SDR Perspective through beautiful figures, simple Math and intuitive explanations. https://wirelesspi.com/book/ Learn about multiple antenna techniques (used in 5G and 6G systems) in 5G Physical Layer - An Easy Guide to Key Technologies through beautiful figures, simple Math and intuitive explanations. https://wirelesspi.com/5g-phy/
