Leveraging Waveform Structure to Develop a Power Scalable AoA Estimation

open access: yesIEEE Open Journal of the Communications Society, 2021
In a mmWave mobile device, power consumption resulting from the high sampling rate is a primary concern for angle of arrival (AoA) estimation solutions. In this paper, we provide a power scalable solution for AoA estimation with structured waveforms in a

Compressive Sensing-Based Secure Uplink Grant-Free Systems

open access: yesFrontiers in Signal Processing, 2022
Compressive sensing (CS) has been extensively employed in uplink grant-free communications, where data generated from different active users are transmitted to a base station (BS) without following the strict access grant process. Nevertheless, the state-

Power Scalable Angle of Arrival Estimation Using Pilot Design With Orthogonal Subsequences

open access: yesIEEE Open Journal of the Communications Society, 2021
Energy efficient array processing is critical to implement feasible solutions for directional communication in a mmWave channel. MmWave channels are highly susceptible to blockage and require frequent angle of arrival (AoA) estimation.

Spectrum-Efficient Distributed Compressed Sensing Based Channel Estimation for OFDM Systems Over Doubly Selective Channels

open access: yesIEEE Access, 2019
In this paper, we deal with channel estimation (CE) for high-mobility orthogonal frequency division multiplexing (OFDM) systems. To make the numerous (unknown) estimation for the high-mobility OFDM systems practicable, the channels are assumed to be time-
