Developing cost-effective solutions to deliver broadband connection to undeserved or under-connected communities using fixed wireless access technology can be achieved by canopy networks. The former can be implemented using MIMO-OFDM technique. The implementations of MIMO-OFDM in systems have shown promising results in terms of system performance improvement. This paper presents high-speed FFT algorithms for wireless personal area network (WPAN) applications which uses high data rate. In WPAN, the FFT/IFFT block plays the major role. To eliminate the huge burden of the computational requirement of the FFT/IFFT process, the divide and conquer algorithm is employed here. This method not only improves the efficiency but is also easy to implement. In this work, the concept of Discrete Fourier Transform is discussed and the same is implemented using MATLAB for the MIMO-OFDM process.
