BER Performance Evaluation of a Mobile WIMAX System Over an ITU-R Pedestrian B Multipath Channel
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2009, Vol 50, Issue 3
Abstract
A realistic modeling of the radio channel’s propagation characteristics proves to be extremely important, especially when one desires to perform an accurate design of a wireless communication system. In this paper, we evaluate and optimize the performances of the ITU-R M.1225 Pedestrian B (Ped.B) channel model for a downlink (DL) mobile WiMAX system, starting from the requirements of certain multimedia services. The influence of parameters such as modulation, coding scheme and cyclic prefix (CP), was analyzed through simulations, in terms of the bit error rate (BER).
