We investigate the incremental relaying protocol in conjunction with relay-selection
cooperative diversity networks with an aim to make efficient use of the degrees of freedom of …

The fundamental capacity limit in cooperative MIMO channels with one source-destination
pair and one relay is investigated. With the channel state information (CSI) at the source and …

We jointly optimize the relay-precoders and decoders with full or partial channel side
information (CSI) in a cooperative network. Specifically, three different CSI assumptions are …

In this paper, we investigate the impact of imperfect channel state information at the
transmitters (CSIT) on the achievable diversity gain in a cooperative relaying channel with …

We propose a set of multiuser two-way relay beam-forming schemes in the cellular network.
While the previous schemes are applicable only when there exist a single base station (BS) …

This paper investigates two issues of cellular engineering for cellular systems enhanced
with two-hop fixed relay nodes (FRNs): spectrum partitioning and relay positioning, under …

This paper examines the shared relay architecture for the wireless cellular network, where
instead of deploying multiple separate relays within each cell sector, a single relay with …

Power allocation strategies are developed for amplify-and-forward cooperative relaying
networks in fading channels. The average signal-to-noise ratio (SNR) and outage …

This letter proposes three smart relaying strategies, including power allocation, continuous
power control, and discrete power control strategies, to mitigate the error propagation …

In this paper, we analyze the symbol-error-rate (SER) performance for a two-user amplify-
and-forward cooperative system. The closed-form SER formulation with PSK signals is …
