Channel estimation and parameters acquisition systems employing cooperative div...
Neves, Darlene MacielThis work investigates new channel estimation schemes for the forthcoming and future generation of cellular systems for which cooperative techniques are regarded. The studied cooperative systems are designed to re-transmit the received information to the user terminal via the relay nodes, in order to make use of benefits such as high throughput, fairness in access and extra coverage. The cooperative scenarios r...
An iterative pilot-data-aided estimator for SFBC relay-assisted OFDM-based systems
Neves, Darlene; Ribeiro, Carlos; Silva, Adão; Gameiro, AtílioIn this article, we propose and assess an iterative pilot-data-aided channel estimation scheme for space frequency block coding relay-assisted OFDM-based systems. The relay node (RN) employs the equalise-and-forward protocol, and both the base station (BS) and the RN are equipped with antenna arrays, whereas the user terminal (UT) is a single-antenna device. The channel estimation method uses the information ca...
