Features include: * A picture of a very clear and thorough about the principles and application of spread spectrum techniques in multi-user mobile communications. * Matlab-based worked examples, and practical training sessions to explain theoretical concepts. * An easy to read explanation of the air interface standards used in IS-95 A / B, CDMA2000, and WCDMA 3G. * Presentation is clear from the high-speed downlink and uplink packet access (HSDPA / HSUPA) techniques used in 3G WCDMA. This book is a very appropriate introduction to the principles of CDMA communications for senior undergraduate and graduate students, and researchers and engineers in industry who wish to develop their skills. * A picture of a very clear and thorough about the principles and application of spread spectrum techniques in multi-user mobile communications. * Matlab-based worked examples, and practical training sessions to explain theoretical concepts. * An easy to read explanation of the air interface standards used in IS-95 A / B, CDMA2000, and WCDMA 3G. * Presentation is clear from the high-speed downlink and uplink packet access (HSDPA / HSUPA) techniques used in 3G WCDMA.
