The spectrum is also severely fragmented across bands and the fragments also have different license conditions. Regulators in India have recently recognized that such spectrum fragmentation is a source of inefficiency for the service providers and have allowed sharing of spectrum among the providers. The genesis of this paper is this regulatory order and it has a three-fold objective. We first study an example spectrum allocation. By assuming GSM-like voice telephony service, we analyse the spectrum holding in one service area in some detail. Using simple calculations, we see that complete pooling of resources by the providers may not be stable-one provider may have a lower blocking probability if it does not form a coalition. This leads us to our second objective of developing analytically tractable partial sharing models where the providers do not pool all their resources. For a probabilistic spectrum sharing model, we analyse a simple system and obtain the partial sharing that will make the coalition stable and Pareto efficient. This model is then extended to a larger system and numerical results from the analytical model are used to obtain additional insights. We then consider a deterministic sharing model for which we also present a similar analysis for this system. We also show that the deterministic sharing system can be analysed via a suitably defined circuit multiplexed network that allows us to use Kelly's Erlang fixed point approximation which in turn provides economic insights. The final objective is to develop a game theoretic model for partial sharing. We provide a Nash bargaining framework for partial sharing. We also discuss some revenue sharing mechanisms when the providers' benefits from partial sharing are asymmetric.","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126568039","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 optimal (minimum) bit error rate (BER) performance in spatially multiplexed MIMO systems can be achieved by employing maximum likelihood detection (MLD) at the receiver end. However, MLD performs an exhaustive search over all possible transmit vectors which is computationally impractical when number of antennas or the modulation order increases. With the motivation of detecting symbol vector in MIMO systems with less computational complexity, we propose an improved multiple feedback successive interference cancellation (IMF-SIC) algorithm in this paper. The multiple feedback (MF) strategy in successive interference cancellation (SIC) is based on the concept of shadow area constraint (SAC) where multiple neighboring constellation points are used in the decision feedback loop if the decision falls in the shadow region. In improved MF strategy, the SAC criteria is checked recursively which results in a better BER performance. Further, to achieve a higher detection diversity, we also propose a multiple branch IMF-SIC (MB-IMF-SIC) algorithm where we incorporate the concept of multiple branch (MB) processing. Simulation results show that the proposed algorithms outperform the existing SIC and MF-SIC based MIMO detectors, and achieves a near optimal BER performance.","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131548383","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}

DASH aims to adapt the bitrate based on the available bandwidth, while minimizing the number of playback interruptions. This is typically achieved with a rate adaptation algorithm, that chooses an appropriate representation for the next video segment. Most of the algorithms use buffer occupancy, measured throughput, or a combination of these to decide the best representation for next segment. In this paper, we investigate the influence of rate adaptation algorithms on the QoE metrics. We implement five different rate adaptation algorithms and experimentally evaluate them under varying bandwidth and network scenarios. We use objective metrics such as, playback start time, average bitrate played, number of bitrate switching events, number of interruptions and duration of the interruptions to assess the QoE. Our results demonstrate that algorithms that consider both throughput and buffer occupancy results in better QoE. Further, we observe that algorithms considering segment size remove the interruptions alongside improving average bitrate played. We observe that due to the mutual dependency of QoE metrics, most of the algorithms do not necessarily improve QoE while selecting the best bitrate.","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116757500","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}
