Abstract :
Digital mobile radio transmission techniques and integrated circuit devices have been developed for application to a digital portable transceiver utilizing narrowband GMSK modulation. Design and performance of a quadrature-type GMSK modulator, and a single chip coherent demodulator are described. For mitigating slow fading, a switching diversity using jitter detection type sensor is proposed and shown to be effective. An experimental portable transceiver, developed to examine the hardware feasibility, is shown.
