    Over the past few years a variety of space diversity system techniques have been considered for the purpose of reducing the rapid fading encountered in microwave mobile radio systems. Basic diversity methods are first reviewed in the framework of mobile propagation effects, and then specific techniques are compared from the standpoint of transmitter power required to achieve a certain performance....

    The theoretical analysis in this paper is based on the assumption that the angles of signal arrival on the mobile receiver are uniformly distributed. From the analysis and experimental studies, we find that if the antenna spacing between two adjacent antennas in a space diversity array is greater than 0.5λ the array configuration does not affect the cumulative distribution curves nor the shap...

    The density of present and projected private vehicular traffic indicates a need for increasingly sophisticated techniques for the detection of, surveillance of, and communication with vehicles. Given these techniques, systems can be implemented to improve traffic flow and service to the motorist. All systems involve the function of data generation, processing and modulation, and transmission. Atte... View full abstract»

    It appears that both substantial improvement in high-speed high-density traffic flow and a decrease in highway accidents can be achieved by highway automation. An essential part of any approach to such automation is a method for the automatic longitudinal control of vehicles. The results of experimental tests of an automatic longitudinal control system in various lead-car overtaking, emergency bra... View full abstract»

  • Some effects of delay and modulation-index mismatch on cochannel FM interference

    The baseband distortion resulting from the cochannel interference of two FM carriers nominally carrying the same modulation is considered. Such distortion was observed to plague VHF mobile telephone service in Phoenix, Ariz. This distortion arises when the landline audio delay and modulation indices of the two transmitters are not closely equalized. Both sinusoidal and Gaussian modulation age anal... View full abstract»
