Performance of TDMA System with SFH and 2-bit Differentially Detected GMSK over Rayleigh Fading channel

초록

In this paper, we deriver an approximate expression for the bit error rate(BER) of 2-bit differentially detected GMSK in the slow frequency hopping spread spectrum multiple access. We can obtain the BER results using the characteristic function of demodulator's output with cochannel interferences, and show that the frequency hopping system has improved performance compared to the frequency reuse FDMA cellular system.
