Quantization Effects on the EVM in EDGE Modulation Standard Gianfranco Avitabile, Nicola Lofù Politecnico di Bari, DEE, via E. Orabona 4 B, 70125, Bari (Italy), phone +390805963854 Abstract -- EDGE standard was born as an evolution of GSM, overcoming the limited data speed. This improvement is obtained using a 3 /8 8-PSK modulation scheme, increasing the available on-air data rate up to 812.5 kbp
