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 autocorrelation and Blackman-Tucky method applies the window after autocorrelation. 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.

The transmitted reference pulse cluster (TRPC) structure for ultrawideband communications enables a more robust autocorrelation receiver (AcR) than a conventional transmitted reference (TR) scheme. In this paper, to further improve the performance of TRPC AcR, we propose a TRPC averaging (TRPC-A) AcR by using a TRPC-A method, which is similar but different from the pulse averaging method used in a conventional TR scheme. The proposed receiver structure is designed in both analog and digital methods, and their implementation complexities are explored. Our analytical and simulation results show that the proposed receiver can greatly improve the performance over the original TRPC receiver. What is more, the required additional implementation complexity of the proposed TRPC-A receiver added to the original TRPC AcR is much less than that of the averaging TR AcR added to conventional TR AcR due to the TRPC signaling characteristics. Therefore, from a practical point of view, the designed TRPC-A AcR is considered as a highly recommended practice, particularly in multiuser access environments.Index Terms-Noncoherent receiver, transmitted reference pulse cluster (TRPC), ultrawideband (UWB).
