Then comes 3G, 3G are the following methods that we have used or modulation schemes that we have used GMSK continued to exist. So, basically these are the methods, these are the things that we have added QPSK, we added 8PSK found that it was very difficult to work with the 8PSK, and also introduced 16 QAM.
इसके बाद 3G में GMSK के अलावा QPSK, 8PSK और 16QAM का उपयोग हुआ।
