A wideband receiver is designed to detect signals over a broad bandwidth. To increase the receiver’s capability of detecting multiple signals, it is a common practice to apply a window to reduce spectral leakage. The modified periodogram applies a window before auto-correlation and Blackman-Tucky method applies the window after auto-correlation. To the best of authors’ knowledge, no one has compared the performance difference in the context of wideband receiver applications. This study finds that the modified periodogram can better enable a receiver to detect multiple signals with a significant power difference at the expense of reduced frequency resolution and sensitivity.
