Introduction
============

Cooperative relaying is an efficient technique to combat fading and path-loss effects in wireless systems. It enables multiple nodes to create virtual multiple-input multiple-output (MIMO) configurations in order to provide spatial transmit and/or receive diversity to single-antenna destinations [@LAN]. Traditional cooperative systems are characterized by the half-duplex constraint that relay nodes cannot receive and transmit data simultaneously, a fact that results to bandwidth loss. In order to overcome this bandwidth limitation, several techniques have been proposed in the literature [@DIN]. Among them, the successive relaying scheme in [@FAN] incorporates multiple relay nodes and proposes a transmission overlap (source-relay, relay-destination) in order to mimic an ideal full-duplex transmission. However, this scheme refers to scenarios with a long distance between the relays and thus inter-relay interference is not considered. An extension of this work is discussed in [@chao_ISIT], where the authors consider that IRI is strong (co-located
