Abstract

We have implemented a non-iterative multitaper sensing hardware core. The multitaper core computes the spectrum as the average of M eigenspectra calculated using Slepian sequences. While more computationally complex than traditional Fourier methods, the multitaper estimation method offers enhanced performance. The working multitaper hardware core was validated on FPGA using over the air RF measurements in the UHF T-Band. The multitaper core has been incorporated into a prototype frequency agile spectrum sensing platform.
