This white paper discusses the fundamentals of the digital modulation schemes used in modern radio frequency communications systems, in particular, APSK and QAM, the fundamentals of EVM, and basics of ...

The RX exhibits less than 8 dB noise figure and achieves EVMs of 5.47-7.21% for 64-QAM signals at 24 Gbps. In over-the-air link testing at 2 m distance, the system achieves less than 4% EVM with both ...

However, there remains a gap between the Gaussian secrecy capacity and the secrecy rate with conventional uniformly distributed discrete constellation input, e.g. amplitude shift keying (ASK) and ...
