Both layers share the same spectrum so that spontaneous intercell interference is unavoidable and needs to be identified and canceled afterwards. In order to address the subsequent interference management, this paper proposes an intercell interference channel estimation scheme for HetNets using compressive sensing (CS). Applying CS to analog orthogonal frequency division multiple access (OFDMA) signals not only achieves lower cost sub-Nyquist sampling but also reduces interference by spreading out the energy of reference symbols of interference link that overlaps data symbols of desired link. Our scheme enhances both desired data symbols and interference channel by canceling the estimations of each other from the received signal in turn iteratively. Simulation results show that our scheme obtains accurate estimation of interference channel and is robust to variations in multipath number and signal-to-interference ratio (SIR).","PeriodicalId":420837,"journal":{"name":"2014 IEEE 15th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130790757","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}

The two transceivers in each pair wish to communicate bidirectionally through several distributed relays. We assume that one of the pairs is the primary pair, meaning that it owns radio frequency spectrum resources and needs to be serviced with a minimum guaranteed rate. The other pair, called the secondary pair, is assumed to own the relay infrastructure. The secondary network allows the primary pair to use the relays in order to establish a bidirectional communication between its transceivers. In exchange for this cooperation, the primary pair assigns a portion of its spectral resources to the secondary pair, for setting up a two-way communication between the secondary transceivers. Assuming amplify-and-forward relaying scheme, the relays collectively build two network beamformers, each of which enables communication between the two transceivers in one pair. To optimally calculate the primary and secondary network parameters, we propose a max-min optimization problem which is amenable to a simple line search based solution with a low computational complexity.","PeriodicalId":420837,"journal":{"name":"2014 IEEE 15th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117136687","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}

The transmitter takes cost constrained actions to probe the transmitter-to-receiver 1 and transmitter-to-receiver 2 channels. Under the probing cost constraint, we provide a lower bound to the secrecy capacity of this setting. The achievability strategy employs a block Markov coding strategy in which the channel state sequence of the previous block is mapped to a key which secures the part of the confidential message to be transmitted in the current block. The challenge in using the state sequence as a source of the key is the fact that the legitimate receivers are not aware of each other's channel state. To that end, we employ a novel strategy in which the transmitter takes XOR of individual keys generated from the state sequences of transmitter-to receiver 1 and transmitter-to-receiver 2 channels and send the XOR-ed key along with the confidential message. We furthermore analyze the trade-off between the achievable secrecy rate and the probing cost constraint. We conclude that there is a linear dependency between the key rate and probing cost constraint.","PeriodicalId":420837,"journal":{"name":"2014 IEEE 15th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114750501","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}
