  • Radio Wave Transmission

    This chapter discusses transmission loss of radio waves starting with the basic form of propagation in free space to transmission loss due to scattering and absorption in natural media such as the troposphere and the ionosphere. Typical measured transmission loss into buildings and vehicles are then given. This is followed by studying various propagation models, which include diffraction loss models, and the effect of ground reflection in the presence of a direct path between the transmitter and receiver. The resultant two‐ray model is derived and its properties are discussed. The two‐ray model is applied to both terrestrial environments and to the magneto‐ionic waves in the ionosphere. Multipath propagation is then discussed for both long range communication via the ionosphere and for indoor and terrestrial communication in built‐up areas.

  • Propagation Effects Modeling and Prediction

    This chapter provides descriptions of prediction models and procedures used for the evaluation of atmospheric propagation degradation on satellite links. It is organized into sections for each of the major weather effects, including atmospheric gaseous attenuation, cloud and fog attenuation, rain attenuation, rain and ice depolarization and scintillation. Two excellent sources are available to provide predictions of attenuation due to gaseous absorption. They are the Liebe Complex Refractivity Model, and procedures developed by the ITU‐R. The ITU‐R provides two procedures for gaseous attenuation prediction: a detailed line‐by‐line summation of the spectral lines of water vapor and oxygen, similar to the Liebe method and, a simpler approximation to the line‐by line approach. The chapter presents two rain attenuation models that have performed well for many diverse regions and types of rain, the ITU‐R rain attenuation model, and the Crane global model.

  • 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.

  • DIGITAL SIGNAL PROCESSING AND MODEM DESIGN CONSIDERATIONS

    This chapter describes the conversion of the analog signal at the input of the demodulator to a digitally sampled version of the signal required for the application of digital signal processing (DSP) techniques in the recovery of the desired information.

The chapter gives a general description of discrete amplitude and time sampling, with a case study of discrete amplitude sampling. It describes specialized applications of discrete‐time sampling involving baseband and bandpass sampling. The chapter also describes subcarrier sampling and Hilbert transform sampling and also discusses nonideal modulator and demodulator implementations. The DSP topics are described under the general heading of multirate signal processing and interpolation. The topics include signal up and down sample rate conversion and the associated filtering requirements, including the cascaded integrate and comb (CIC) filter, polyphase‐matched filtering, and Lagrange interpolation.

  • Rain Fade Mitigation

    Space communications systems operating above 10 GHz are subject to weather dependent path attenuation, primarily rain attenuation, which can be severe for significant time periods. Fixed line‐of‐site satellite restoration techniques can be divided into two types or classes: power restoral and signal modification restoral. This chapter reviews several restoration techniques, of both types, available to the systems designer for overcoming severe attenuation conditions on earth‐space links. It discusses the power restoral techniques, listing in approximate order of increasing complexity of implementation, beam diversity, power control, site diversity, and orbit diversity. The second general type of link restoral involves the modification of the communications signal characteristics to realize performance improvement in the presence of link fading and other path degradations. The chapter discusses the following signal modification restoral techniques namely frequency diversity, bandwidth reduction, time diversity, adaptive forward error correction, and adaptive coded modulation (ACM).
