Joint Modeling of Received Power, Mean Delay, and Delay Spread for Wideband Radio Channels [PDF]
IEEE Transactions on Antennas and Propagation, 2021 We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental

Computation of Delay Spread using 3D Measurements [PDF]
1999 IEEE 49th Vehicular Technology Conference (Cat. No.99CH36363), 1999 This paper proposes a new method for computing the delay spread (DS) of the mobile radio channel. The method utilizes a 3D measurement of the received signal at a given position and assumes knowledge of the receiver antenna radiation pattern.

Reducing group delay spread using uniform long-period gratings. [PDF]
Sci Rep, 2018 AbstractDespite the promise of an orders-of-magnitude increase in transmission capacity, practical implementation of mode-division multiplexing faces a number of challenges. The most important among them is the complexity of digital signal processing (DSP) for compensating mode crosstalk and modal dispersion.

Delay Tracking of Spread-Spectrum Signals for Indoor Optical Ranging [PDF]
Sensors, 2014 Delay tracking of spread-spectrum signals is widely used for ranging in radio frequency based navigation. Its use in non-coherent optical ranging, however, has not been extensively studied since optical channels are less subject to narrowband ...
