【Abstract】 GSM/EDGE is proposed for the evolution of the GSM to 3G. The modulation scheme to be used is 3π/8 offset 8PSK and the pulse shape filter is linearized Gaussian filter.This paper will compare the performance between the GSM/EDGE-8PSK and raised cosin filterd normal 8PSK signal.From the result,we can see,at the same BER,comparing to use normal raised cosin pulse shape filter,EDGE-8PSK needs more SNR about 10dB.therefore,EDGE-8PSK can only provide high date rate service at high SNR condition.更多还原
