High Throughput of WiMAX MIMO OFDM Including Adaptive Modulation and Coding

WiMAX technology is based on the IEEE 802.16 specification of which IEEE 802.16-2004 and 802.16e amendment are Physical (PHY) layer specifications. IEEE 802.16-2004 currently supports several multiple-antenna options including Space-Time Codes (STC), Multiple-Input Multiple-Output (MIMO) antenna systems and Adaptive Antenna Systems (AAS). The most recent WiMAX standard (802.16e) supports broadband applications to mobile terminals and laptops. Using Adaptive Modulation and Coding (AMC) we analyze the performance of OFDM physical layer in WiMAX based on the simulation results of Bit Error Rate (BER), and data throughput. The performance analysis of OFDM PHY is done. In this paper, an extension to the basic SISO mode, a number of 2 by 2 MIMO extensions are analysed under different combinations of digital modulation (QPSK, 16QAM and 64QAM) and Convolutional Code (CC) with half, two-third and three quarter rated codes. The intent of this paper is to provide an idea of the benefits of multiple antenna systems over single antenna systems in WiMAX type deployments.
