Produktbeschreibung

The definitive guide to problem-solving in the design of communications systems In Algorithms for Communications Systems and their Applications, 2nd Edition, authors Benvenuto, Cherubini, and Tomasin have delivered the ultimate and practical guide to applying algorithms in communications systems. Written for researchers and professionals in the areas of digital communications, signal processing, and computer engineering, Algorithms for Communications Systems presents algorithmic and computational procedures within communications systems that overcome a wide range of problems facing system designers. New material in this fully updated edition includes: * MIMO systems (Space-time block coding/Spatial multiplexing /Beamforming and interference management/Channel Estimation) * OFDM and SC-FDMA (Synchronization/Resource allocation (bit and power loading)/Filtered OFDM) * Improved radio channel model (Doppler and shadowing/mmWave) * Polar codes (including practical decoding methods) * 5G systems (New Radio architecture/initial access for mmWave/physical channels) The book retains the essential coding and signal processing theoretical and operative elements expected from a classic text, further adopting the new radio of 5G systems as a case study to create the definitive guide to modern communications systems.
