Abstract: In this letter, we take the lead in investigating the average AoI performance for polar coded status updates over the additive white Gaussian noise (AWGN) channels. Compared with the non-automatic repeat request (non-ARQ) scheme, the… read more here.

DOI: 10.1109/tsp.2021.3110655
Abstract: This paper proposes a Kalman filtering (KF)-based combining scheme for multiple-input multiple-output (MIMO) systems with hybrid automatic repeat request (ARQ). In the state-space model, the change of a transmit signal vector in consecutive transmission time… read more here.

DOI: 10.1109/twc.2019.2899303
Abstract: Scheduling the transmission of status updates over an error-prone communication channel is studied in order to minimize the long-term average age of information at the destination under a constraint on the average number of transmissions… read more here.
