Study of WiMAX Physical Layer Under Adaptive Modulation Technique Using Simulink
IEEE 802.16e WIMAX (Worldwide Interoperable Microwave ACcess) is the upcoming wireless system which can offer high speed voice, video and data service up to the customer end..It offers both LOS&N-LOS wireless communication. By using WIMAX Technology the authors can overcome the limitation of short coverage area, lack of security and low data rate. The aim of this paper is the performance evaluation of an WIMAX system under different combinations of digital modulation and different communication channels AWGN and fading channels. And the WIMAX system incorporates Reed-Solomon (RS) encoder with Convolutional encoder with 1/2and 2/3 rated codes in FEC channel coding.
