SINOPSIS

The error vector magnitude (EVM) measure the performance of communication system. It is also known as relative constellation error (RCE). This paper is going to perform modulation accuracy along with spectrum emission mask and flatness on IEEE802.11ac waveform in terms of RMS EVM. Here a communication system model is designed with various parameters to perform simulation. 5 VHT (very high throughput) packets are used for transmission. Measurement of RMS EVM performed by varying filter length and high power amplifier (HPA) back-off for 256-QAM (256-quadrature amplitude modulation). This paper also shows the RMS EVM for 64QAM, 128QAM, 256QAM, and 512QAM. Kaiser window with design parameter 0.5 implemented for the same.
