Kurzbeschreibung
Building on the success of the first edition while filling a gap in the current literature, Mobile Radio Channels, Second Edition provides an understanding of the key issues currently being investigated in the area of mobile fading channel modeling. Including coverage of the fundamentals of stochastic and deterministic channel models as well as modeling and simulation of frequency-nonselective fading channels, this updated guide gives scientists and postgraduate students alike several new chapters, numerous illustrations, and MATLAB programs for the evaluation and simulation of mobile fading channels.
