  • Abstract
    Investigates bit error rate (BER) performance of a GMSK frequency detection system. The channel measurement information (CMI) for a bit in the received block is calculated from samples of the received signal envelope (Rs) and the demodulator output (eye level). The CMIs of eye level*Rs and of Rs2 are investigated, and the decoding performances for the CMIs are compared using the Hamming (7, 4) code in nonfading (static) and fading channels in laboratory experiments.
