Performance of MIMO-OFDM Transmission System on Wireless Networks
A detailed study of the performance of MIMOOFDM transmission on WLAN physical layer specified in IEEE 802.11n, WiMAX (IEEE 802.16-2009) physical layer specified in 802.16 and LTE downlink physical channel has been carried out using MATLAB Simulink. The WLAN and WiMAX system incorporates Convolution coding with 1/2 and 2/3 rated codes. The LTE incorporates Turbo coding with 1/2 and 2/3 rated codes. Orthogonal Frequency Division Multiple (OFDM) accesses uses adaptive modulation technique such as QPSK,16-QAM and 64- QAM, on the physical layer of WLAN, WiMAX and LTE and the concept of cyclic prefix that adds additional bits at the transmitter end.
