Quadrature Amplitude Modulation (QAM) isn't a specific technology. It's a method for encoding, sending, receiving, and ...

We present an implementation of Quadrature Amplitude Modulation (QAM) signal modulators using Field Programmable Gate Array (FPGA). The modulator is targeted at the low-level "RTL based" ...

The subcarrier QAM modulation is specified each clock cycle to accommodate systems supporting adaptive bit loading. The QAM channel state information (CSI) can be specified on the same clock cycle as ...
