Analysis of WiMAX Physical Layer Using Spatial Multiplexing
Broadband Wireless Access (BWA) has emerged as a promising solution for
providing last mile internet access technology to provide high speed internet
access to the users in the residential as well as in the small and medium sized
enterprise sectors. IEEE 802.16e is one of the most promising and attractive
candidate among the emerging technologies for broadband wireless access. The
emergence of WiMAX protocol has attracted various interests from almost all the
fields of wireless communications. MIMO systems which are created according to
the IEEE 802.16-2005 standard (WiMAX) under different fading channels can be
implemented to get the benefits of both the MIMO and WiMAX technologies. In
this paper analysis of higher level of modulations (i.e. M-PSK and M-QAM for
different values of M) with different code rates and on WiMAX-MIMO system is
presented for Rayleigh channel by focusing on spatial multiplexing MIMO
technique. Signal-to Noise Ratio (SNR) vs Bit Error Rate (BER) analysis has
been done.Comment: 14 pages, 12 figures, 1 table; International Journal of Wireless &
