A Wideband Sliding Correlation Channel Sounder in 65 nm CMOS: Evaluation Board Performance

no code implementations12 Jun 2021 Dipankar Shakya, Ting Wu, Michael E. Knox, Theodore S. Rappaport

This paper presents a compact sliding correlation-based channel sounder baseband built on a monolithic integrated circuit (IC) using 65 nm CMOS, implemented as an evaluation board achieving a 2 GHz RF bandwidth.

Dense Urban Outdoor-Indoor Coverage from 3.5 to 28 GHz

no code implementations8 Mar 2022 Dipankar Shakya, Dmitry Chizhik, Jinfeng Du, Reinaldo A. Valenzuela, Theodore S. Rappaport

For 28 GHz with 1 W/polarization transmit power in the urban street grid, the downlink data rates for 90% of outdoor users are estimated at over 250 Mbps.

Waste Factor: A New Metric for Evaluating Power Efficiency in any Cascade

no code implementations2 Sep 2023 Mingjun Ying, Dipankar Shakya, Hitesh Poddar, Theodore S. Rappaport

Our study further explores how insertion loss of components in a cascaded communication system influences $W$ at 28 GHz and 142 GHz along with the data rate performance, evaluated using the consumption efficiency factor (CEF).

A Sub-Terahertz Sliding Correlator Channel Sounder with Absolute Timing using Precision Time Protocol over Wi-Fi

no code implementations2 Sep 2023 Dipankar Shakya, Hitesh Poddar, Theodore S. Rappaport

Additionally, a periodic drift correction algorithm is applied to eliminate PDP sample drift and achieve sub-nanosecond timing accuracy for MPC delays.
