OFDM Physical Layer Simulation of IEEE 802.16-2009(Mobile WiMAX)
Автор:Sanjay Chaudhary Год: 2012 Издание:LAP Lambert Academic Publishing Страниц: 104 ISBN: 9783659208393 With the development in internet applications and multimedia technology, users are accustomed to high-speed broadband at home and work and demand similar services even in nomadic or mobile environment. Mobile WiMAX provides broadband wireless access with mobility, large coverage and security. WiMAX physical layer is based on Orthogonal Frequency Division Multiplexing which mitigates multipath and eliminate intersymbol interference with the help of cyclic prefix. Scalable OFDMA on its physical layer allows data rate to scale with available channel bandwidth. WiMAX supports a number of modulation (BPSK, QPSK, 16-QAM & 64-QAM) and forward error correction coding scheme and can operate in both line of sight and non-line of sight environments. In this book, the performance of physical layer of mobile WiMAX is evaluated at different modulation schemes, coding rate, FEC coding schemes and noise levels with models of multipath fading channel based on the specification of IEEE Std....
