Rain fade slope predicted from rain rate data

A key parameter of the statistics of the rate of change of rain attenuation (“fade slope”) on satellite links is the variance of relative fade slope. This paper shows how this parameter can be derived from rain rate measurements without the use of satellite beacon measurements. Relating rain rate directly to attenuation would give unrealistic results. A theoretical model to ...

  • Trends in Wireless Communications

    This chapter includes a summary of the history and recent trends in wireless communications especially on mobile cellular systems. The basic transmission problems and solutions are summarized in the physical and network layers. The fundamental limits define the upper performance bounds for spectral and energy efficiency. Regulation and standardization is needed so that the finite frequency resource is used efficiently, and the systems work together even in different continents. We expect that in the future the radio systems will be more intelligent but the level of cognition will depend on the available energy resources.

  • Computer‐Aided Synthesis of Characteristic Polynomials

    This chapter discusses the synthesis of the characteristic polynomials of lowpass lossless prototype filters using an efficient computer‐aided optimization technique. It specifies an unconstrained artificial function for the optimization process that includes the objective function, as well as the inequality and equality constraints. The chapter develops the appropriate objective functions for optimization to generate the known classes of filter functions. The technique described for the computer‐aided optimization of characteristic polynomials for minimum phase filters is equally applicable for linear phase filters, both symmetric and asymmetric. The efficiency of this procedure is demonstrated by including examples of the classical Chebyshev and elliptic function filters as special cases of the design procedure. The computed critical frequencies are specified in Appendix 4A. These data add to the range of unified design charts and also provide guidelines for developing software to synthesize characteristic polynomials for filters with arbitrary amplitude and phase response.

  • Characterization of Propagation Channels

    The reliable knowledge of the propagation channel is the foundation of the design and analysis of any wireless communication system. This chapter provides a unified and conceptually simple explanation of a morass of concepts around wireless channels. In the context of wireless radio channels, wide‐sense stationary uncorrelated scattering (WSSUS) is usually assumed. Wireless channels are the real environments in which the transmitter (Tx) and receiver (Rx) operate. Path loss is the attenuation in the transmitted signal while propagating from the Tx and Rx. Multipath propagation is when the transmitted signal reaches the Rx by two or more paths. The characterization of the multipath fading channel is essential for understanding and modeling it properly. The most important and often‐used approximate descriptions are the first‐order received envelope and phase PDF of multipath fading and some second‐order descriptions of multipath fading, such as the level cross rate (LCR), average fading duration (AFD), and the correlation properties.


    This chapter introduces different kinds of coupled lines to design balanced filters with ultra‐wideband (UWB) or wideband differential‐mode bandpass responses and high common‐mode suppression. It discusses the novel filters that include UWB balanced filters combining UWB bandpass filter (BPF) and UWB bandstop filter(BSF), wideband balanced filters using coupled line stubs, wideband balanced filters with internal cross‐couplings, wideband balanced filters using stub‐loaded ring resonators (SLRRs), and wideband balanced filters using modified coupled feed lines (MCFLs) and coupled line stubs (CLSs). Balanced filter can be realized by combining the traditional BPF and BSF. To achieve high selectivity in differential mode and enhanced rejection in common mode, more transmission zeros should be introduced. Another simple and innovative approach is proposed to design balanced wideband filter with high selectivity and common‐mode suppression. The chapter shows the circuit model and layout of the proposed balanced BPF, which contains two SLRRs.
