Because fine-tuning the parameters of a system is critical to a developer's success, Performance Optimization of Digital Communications Systems examines particular optimization problems in digital communications, presenting analytical techniques in combination with SystemView and MATLAB® simulations. Consisting of ten chapters, this monograph presents a unique method for determining the quality of a communications channel - a great advantage to any company that uses this method. The book presents a method for the transmission of proprietary data. It also describes the means to reduce the peak-to-average power ratio and introduces optimal phase shifters for multicarrier communication systems. This volume contains numerous illustrations and includes appendices that offer optimization puzzles, MATLAB scripts, and some newly discovered properties of flat-spectrum and spectrum-shaped waveforms.
