Efficient Implementation of MIMO using OFDM Applications

M. Arun Kumar

Abstract: Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) technology is an attractive transmission technique for wireless communication systems with multiple antennas at receiver and transmitter. The reliability of Data rate and diversity can be increased along with the stability for multi-path signals. The efficient implementation of a Low-Power 64-point Pipeline FFT/IFFT processor adopting a single-path delay. To achieve a ROM-less FFT/IFFT processor; thus less power is consumed using the complex multiplier reconfigurable and bit-parallel multipliers. Based Header channel estimation with maximum likelihood algorithm is chosen in consideration of hardware feature as well as communication theory. Simple logic is used in Pipeline architecture includes one adder and channel memories without redundancy. Can be reduced the complexity from O (n2) to O (1) it saves 43 percent of the hardware resources and achieves a better performance in the architecture.
