    In our highly mobile society, the provision of voice and data communications to people away from their wireline telephones has become a major communications frontier. Some emerging radio systems, e.g., cellular mobile radio, cordless telephone, and radio paging, have begun to penetrate this frontier. However, each of these approaches only partially satisfies portable communication needs. That is, ... View full abstract»

    A statistical model for a land mobile satellite link is described. The model assumes that the amplitude of the line-of-sight component under foliage attenuation (shadowing) is lognormally distributed and the received multipath interference has a Rayleigh distribution. Expressions for the level crossing rate and average fade duration are given. Comparison between results calculated from the model a... View full abstract»

    In a digital mobile radio transmission, long-delayed multi-path propagation causes frequency selective fading, resulting in signal waveform distortion and hence bit error rate (BER) degradation. Comparison of multipath distortion among various digital modulation techniques (binary, quaternary, offset quaternary, and minimum phase shift keying (BPSK, QPSK, OQPSK and MSK)) is made using a two-ray pr...

    An analysis of the effect of multiple tone interferers on the bit error rate (BER) in a frequency-hopped multiple frequency shift keying (FH-MFSK) spread spectrum communication is given. A constant insertion rate detection strategy has been considered and a matched tuned filtering used in the receiver. We have obtained results in the 20 MHz (one-way) bandwidth with a data rate of 32 kbit/s and a R... View full abstract»

    Frequency inversion of the voice spectrum is a common method of providing simple privacy on single channel radio links. When combined with exponential modulation this method produces an increase in system noise of 8.00 dB. Alternative inversion methods are analyzed. The methods involve partitioning the voice spectrum into two halves, inverting one or both of these halves and, in some cases, incorp... View full abstract»
