Hiroshi Harada, Ramjee Prasad
ISBN: 1580530443
May 2002

This cutting-edge, first-of-its-kind resource gives you a comprehensive understanding of the simulation and evaluation methods used for today’s mobile communication systems. Written by two highly regarded experts in the field, the book focuses on the performance of both the physical and protocol layer transmission scheme. It defines and presents several invaluable simulation tools written in MATLAB® code, along with clear examples that explain their use.

You get in-depth discussions on digital modulation techniques, including BPSK, QPSK, OQPSK, MSK, GMSK,and QAM by using simulation programs. Moreover, the book also explains the history and configuration of both OFDM and CDMA transmission scheme, discusses multiple access protocols, cellular telecommunication systems, and introduces cutting-edge software radio communication systems. This practical reference is packed with over 240 equations and 160 illustrations.

Samsung Instinct S30 for Sprint

The Samsung SPH-M810 Instinct S30, often referred to as the Instinct Mini in the rumor mill, is a new version of the very popular Samsung Instinct that includes most all of the same features, but packaged in a far nicer design. If the spec sheet of the original left you wanting for more, the Instinct S30 might not interest you, but if you were turned off by the original’s plain Jane design, then the S30 might be just the ticket.
