Sparse Blind Demixing for Low-latency Signal Recovery in Massive Iot Connectivity

ICASSP 2019accepted

Internet-of-Things (IoT) networks are envisioned to typically include a massive number of devices with sporadic and low-latency uplink service needs. This paper presents a blind demixing approach to support the data recovery of multiple simultaneous and unscheduled device transmissions without a pri…

Robust receiver design based on FEC code diversity in pilot-contaminated multi-user massive MIMO systems

ICASSP 2016accepted

This work investigates robust receiver design against pilot-contaminated channel estimation in large multi-antenna systems. Given bounded channel estimate errors, we tackle the multi-user detection problem by presenting a novel idea of exploiting the forward error correction (FEC) code diversity. Un…

Diversity combining in wireless relay networks with partial channel state information

ICASSP 2015accepted

We develop a novel diversity combiner for joint reception in wireless relay networks with unknown relay-to-destination channel. The partially available channel information poses an obstacle for utilization of the relay diversity. We tackle this problem by formulating a unified second-order cone prog…
