Design of OFDM MIMO Transreciever Model With Fast Fourier Transform in SIMULINK
Abstract
The Orthogonal Frequency Division Multiplexing (OFDM) having multicarrier transmission. OFDM is useful in Frequency Selective Fading to reduce robustness. It having N number of non-overlapping sub channels. By combining of Multiple Input Multiple Output that is MIMO OFDM
Transmit high data at a time to increase Data rate.
[9]For OFDM MIMO transceiver operation FFT and IFFT is used. Using different parameters like Constellation , Convolutional code rate and the MIMO Parsing method transceiver operation is done.16 QAM at ½ code rate for 48 Mbps data rate with Spatial multiplexing. FPGA is used for Hardware Co-simulation.
