Abstract

The GSM system has evolved to the GSM EDGE system which increases the data rate with new modulation and coding schemes. This increase is achieved by improving the spectral efficiency of the system at the expense of power efficiency. In this paper, we propose the use of a spectral and power efficient modulation scheme, a combination of frequency and phase modulation NFSK/LPSK, to further increase the data rate of the current GSM EDGE system. We show that by using the current EDGE channel coding and a 2FSK/8PSK modulation scheme the data rate can be increased 33% with just 2 dB degradation in E_b/N₀ ratio with equal bit error rate in the AWGN channel.
