Opis

The objective in this book is to analyze synchronization algorithms for OFDM systems using the example of the standard IEEE802.11a (WLAN). The basic principles for OFDM systems are described and an overview on the recent technologies is given. Impairments that may occur in a digital transmission are explained such as time, frequency and phase errors and their consequences are discussed in detail. The state-of-the-art synchronization techniques for the time domain are summarized, whereas the implementation aspects are always taken into account. A developed environment is described, which has been written in the language SystemC to simulate a transmission system with fixed-point representation. Furthermore, the implemented synchronization algorithm is explained in detail and the results are shown.
