Impact of frequency-selective fading on digital land mobile radio communication at transmission rates of several hundred kbit/s

Based on measurements reported from New York City and the city of Berne, Switzerland, and its outskirts, computer simulations of the mobile radio channel transfer functions were performed. It is demonstrated that the impulse response may suffer considerably from large variations of the channel characteristics. It is concluded that powerful means of signal processing are necessary to safeguard digital land mobile radio communication at transmission rates of several hundred kbit/s.
