Field experimental results of narrowband digital FM signal transmissions at 1-45 GHz carrier frequency are reported. A 16kbit/s Gaussian-filtered MSK (GMSK) was employed for the modulation scheme. Transmitted signals were received by a two branch space diversity receiver using improved frequency-detection schemes. The measured bit-error rates (BERs) are presented.
