    Schemes for accessing the message channels of base stations in a cellular communication system are considered. Detailed analysis is given for a fixed channel assignment scheme with collision type request channels. The probability Pfthat a request fails to secure a message channel is considered as a performance criterion. That fraction of bandwidth allocated to request channels, which mi... View full abstract»

    The spectrum efficiency of a frequency-hopped multilevel frequency-shift keying (FH-MFSK) spread spectrum modulation technique proposed for use in mobile radio systems is evaluated. The analysis assumes randomly chosen address vectors, a perfect synchronization at the receiver, and noncoherent detection. With perfect transmission where the only degradation is due to mutual interference, the effici... View full abstract»

    An extensive study of digitized speech transmission over existing VHF FM mobile radio sets is presented. Objective criteria expressed in terms of bit error rate (BER) are determined for the performance evaluation of analog FM radios when transmitting digital voice. These criteria are used to define the technical characteristics such as the receiver sensitivity, co-channel rejection, and adjacent c... View full abstract»

    A small solid-state radar combined with a microprocessor makes possible collision-mitigation braking and automatic headway control in cars of the future. The collision-mitigation function involves the application of antiskid brakes under conditions where, based on radar and other sensor inputs, it is certain that a severe collision will take place. The decision-making algorithm is optimized to pre... View full abstract»

    The performance of linear induction motors subject to velocities normal to the track are calculated both by finite element and Fourier analysis techniques. Results yielded by the two methods for the case of a small traction linear machine are compared. The response to a step increase in air gap of a high speed vehicle levitated and driven by a linear induction machine supplied with constant curren... View full abstract»

    A computer model is described that predicts the reaction forces developed by single-sided linear induction motors (SLIM's) with solid iron secondaries. The model predictions are compared with test results obtained from three separate SLIM investigations covering a wide range of operating conditions and SLIM design parameters. The results demonstrate the basic validity of the model and its applicab... View full abstract»
