Multi-FFT demodulation can be applied with either coherent or differentially coherent detection. Differentially
coherent detection may have advantages on time-varying channels where coherent detection suffers from channel estimation errors. Differential encoding is best performed in the frequency domain, i.e. across the OFDM carriers. In the source code package available for download at http://millitsa.coe.neu.edu/?q=projects, multi-FFT demodulation is implemented with differentially coherent detection and multiple receiving elements (spatial diversity).
