2-bit 차동 복조 SFH/GMSK 시스템의 오율분석

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.
