By sharing radio resource with cellular user equipments (CUEs), D2D communications can significantly enhance the overall spectral efficiency. However, the resulting mutual interference may cancel or even outweigh the gain brought by D2D communications. In this paper, we avoid the interference through a well designed resource allocation scheme. We formulate the uplink resource allocation problem where more than one D2D pair can share the same resource with one CUE under the constraint that the SINR requirements of CUEs and admitted D2D pairs are satisfied. The optimization resource allocation is shown to be NP-hard, and an interference degree based Greedy heuristic Resource Allocation algorithm (GRA) is explored to maximize the number of admitted D2D pairs by properly selecting a group of D2D pairs for each CUE. Simulation results show the efficacy of the proposed algorithm.","PeriodicalId":121230,"journal":{"name":"2013 IEEE/CIC International Conference on Communications in China - Workshops (CIC/ICCC)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121558885","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 heterogeneous network (Hetnet) has been widely accepted as an effective wireless networking method to improve system capacity. However, multi-tier networking architecture and the great number of small cells coexisting with macrocell make the interference management and spectral resources management more complex. The corresponding problems thus draw great attentions in 3GPP standardization process. In this paper, we introduce the cloud radio access network (Cloud-RAN), which is seen as a low cost delivery method of cellular networks, into spectral resources management and interference management of Hetnet. To achieve effective spectral resources management and interference management in this architecture, the following contributions are further made: 1) the spectral resources allocation optimization problem of Hetnet is constructed, comprehensively considering the mutual interference, spectral efficiency and quality of service (QoS); 2) to solve the optimization problem, we propose the probability weighted based spectral resources allocation algorithm; 3) to analyse the influence of the proposed algorithm to the infrastructure network (e.g., macrocell), the closed-form outage probability of macrocell users is derived. Finally, the comparison results show that the proposed algorithm has higher frequency reuse efficiency and lower outage probability of macrocell users.","PeriodicalId":121230,"journal":{"name":"2013 IEEE/CIC International Conference on Communications in China - Workshops (CIC/ICCC)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122313056","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 problem is modeled as maximizing the worst SINR of BUs while meeting SINR requirements of GUs and limiting total power of base station (BS). We figure out feasibility of the problem with solving the max-min-weighted-fairness (MMWF) problem. If it is feasible, we propose a heuristic removal algorithm to turn the infeasible problem into a feasible one; otherwise, we study the relation between the feasible problem and the MMWF problem by introducing auxiliary variables. Based on that relation, a fixed-point iterative algorithm converging to the optimal solution is proposed to solve the feasible problem. Besides, the algorithm can be implemented distributively. Simulation results reveal the effectiveness of the heuristic removal algorithm, and the optimality and fast convergence of the fixed-point iterative algorithm.","PeriodicalId":121230,"journal":{"name":"2013 IEEE/CIC International Conference on Communications in China - Workshops (CIC/ICCC)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132787380","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}

To process the received signal digitally, high sampling rate analog-digital-converters (ADC) are required. Due to the high complexity and large power consumption, employing multibit high-rate ADC is impractical. However, monobit ADC is appropriate. The optimal monobit digital receiver has already been proposed. This kind of receiver has been derived under the assumption that the intersymbol interference (ISI) either does not exist or can be regarded as random noises. When encountered with heavy ISI, these receivers are not excellent as we expected. There are many approaches to solve the ISI problem in regular communication systems. When applied to monobit systems, unfortunately, most of them turned out to be unavailable due to the great loss of quantification. Decision feedback equalization (DFE) is an effect way to deal with ISI in monobit digital systems. In this paper, we propose an algorithm that combines Viterbi decoding and DFE together for monobit receivers. In this way, we suppress the impact of ISI effectively, thus improving the bit error rate (BER) performance. In addition, we introduce a method called state expansion by which better BER performance can be achieved. Under the condition of perfect channel state information(PCSI), the simulation results show that the algorithm has about 1dB SNR gain compared to separate monobit BPSK demodulation with convolutional decoding and 1dB SNR loss compared to the BER performance of optimal monobit receiver in the channel without ISI. Compared to the full resolution detection in fading channel without ISI, it has 3dB SNR loss after state expansion. Under the CSI that achieved from iterative evaluation, both the performance of optimal monobit receiver and joint receiver have 1dB loss compared to that of PCSI.","PeriodicalId":121230,"journal":{"name":"2013 IEEE/CIC International Conference on Communications in China - Workshops (CIC/ICCC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127141156","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}
