详细说明： The first part of this Master’s thesis details the analysis of a generic OFDM system. An analytical OFDM system model is expressed using matrix-vector notation. Several channel models are analyzed and added to the transceiver simulator. The extreme programming methodology is used and evaluated during the development of the MATLAB simulator for the OFDM system model. The second part of the thesis is dedicated to decreasing the simulation time. The most computationally complex part of the simulator is offloaded to an FPGAbased har dware accelerator by using hardware/software co-design techniques. A structured analysis advocated by the Rugby model is followed to define the activities and abstraction levels. The concepts of co-design are presented in a literature study. The fixed precision performance of the Jakes’ channel simulator algorithm is analyzed. The algorithm is optimized in order to reduce precision requirements. The simulator is written in Handel-C programming language and compiled into hardware by using DK Suite IDE. Finally, an analysis of performance increase is performed. ...展开详情收缩
