    An analytical method is presented for the error probability evaluation that can be used in many cases to reduce significantly the computation time with respect to that required by simulation techniques. The method can take into account thermal noise, intersymbol interference caused by intermediate frequency (IF) and baseband (BB) filterings, multipath propagation with typical delay spreads, Raylei...

    A series of error sequence measurements in a typical mobile radio channel has been conducted to study the time distribution of transmission errors. E.N. Gilbert's (1960) and B.D. Fritchman's (1967) digital communication channel models are shown to describe adequately the observed error bursts occurring in the mobile radio channel. An estimation method based on the gradient algorithm is proposed fo... View full abstract»

    A method of designing low-speed single-sided linear induction motors (SLIMs) for urban transit with maximum speed of 70 km/h is described. The SLIMs can be used not only for Maglev vehicles, but also for the vehicles of the LIM/wheel systems in which the SLIMs are used for propulsion and the wheels for suspension and guidance. The effects of varying principal design parameters on the performance c... View full abstract»

  • Degradation in FH-MFSK mobile radio system capacity due to Rayleigh fading and log-normal shadowing

    Publication Year: 1988, Page(s):130 - 134

    A frequency-hopped multilevel frequency-shift-keying (FH-MFSK) system has been proposed for digital mobile radio communications. The performance of the system is evaluated by studying average probability of error caused by transmission impairments. The degradation in performance due to Rayleigh fading and log-normal shadowing environments is determined. With perfect transmission, where the degrada... View full abstract»

  • UHF measurement of seasonal field-strength variations in forests

    Field-strength variations of land mobile radio systems are particularly large in forests. A number of field-strength measurements along the same road sections were performed periodically in 1983 and 1985 to estimate this variation in the UHF range. Characteristic figures are derived from these measurements View full abstract»

    Several soft-decision receiver structures are proposed for coded direct-sequence differential-phase-shift-keyed (DPSK) spread spectrum systems operating over pulse-jammed channels. The performance of the maximum-likelihood soft-decision receivers and a number of suboptimal soft decision receivers is considered. Soft-decision receivers require channel side information for satisfactory performance i... View full abstract»

    Requirements for the instrumentation to measure railway track geometry are given, and alternative implementations are considered. A compensated accelerometer arrangement that replaced an earlier vertical-reference gyroscope used to establish a horizontal reference is described. Theoretical performance estimates for the new implementation are presented View full abstract»

  • Measurements of path loss at 910 MHz for proposed microcell urban mobile systems

    Measurements of propagation path loss at 910 MHz were made in an urban area (Ottawa, Canada), using transmission from an antenna at street-lamp height (8.5 m) to a mobile receiving antenna at a height of 3.65 m. The received power was sampled about once per meter. On the same street as the transmitter, the received power was found to approximate the free-space value, with occasional 10 dB fades. O...
