Previous work on multi-antenna relays either assumes that only one relay available in the network without benefiting from relay cooperation or all relays are used to assist the source transmission resulting extensive loss of spectral efficiency and high burden to the diversity combiner. For multi-relay cooperative networks, adaptive incremental relaying (IR) is considered in this paper as the cooperative strategy for multiple fixed relays performing uncoded decode-and-forward (DF). Unlike previous work on adaptive IR, relays employ multiple antennas to enhance the received signal quality. Then a small number out of all available relays are used instead of them. In determining whether the rest of relays are needed, two kinds of mechanisms are considered, namely decoding and threshold test that characterize different operational complexity at the destination. For both cases, we derive closed-form expressions of the average outage probability over Rayleigh fading channels. Numerical and simulation results are presented to demonstrate the effectiveness of adaptive IR in the context of multi-antenna relays.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126589612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the random deployments of these autonomous devices has complicated the current network topology and thus will lead to intensified interference to the in-use macrocell networks. In this paper, we propose a Stackelberg game (SG)-based power control scheme to impose regulation on these noncooperative femtocells. Specifically, a network power controller (NPC) is assumed as the leader of the SG and the femtocells it connects to play as the followers. By pricing for the femtocells power consumption, the NPC tries to minimize the transmit power of the femtocell network under both the quality of service (QoS) constrains at femtocell terminals and the sum interference constrain at the macrocell terminals. We prove that an unique Stackelberg equilibrium (SE) exists in this game and a distributed algorithm that converges to the SE is further proposed. Numerical results show that besides the fast convergence property, our algorithm greatly reduces the transmit power of femtocells and therefore, improves the power efficiency of the femtocell network as much as 10 times, compared with that of the pure non-cooperative game scheme.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123418270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we analyze the opportunistic transmission among the multiple secondary receivers (SRs) in order to improve the performance of secondary system. The secondary transmitter ST attains the opportunity of spectrum sharing by relaying the primary users' messages. Network coding and superposition coding are utilized at ST that superimposes its own message on network-coded primary signals. ST transmits its own signal to a best secondary receiver b*, SRb*, which is selected with opportunistic strategy. In this paper, the probabilities of outage region are computed for MAC as well as the achievable region. Based on the probabilities of these regions, we analytically derive the outage probabilities for both the primary and secondary systems under the cognitive relaying protocol with opportunistic secondary transmission in primary MAC.","PeriodicalId":154082,"journal":{"name":"2012 1st IEEE International Conference on Communications in China (ICCC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124212598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
