Building on work of Meshkati, et al., wherein the tools of game-theory are used in order to achieve energy-efficiency in a simple synchronous code division multiple access system, system asynchronism, the use of bandlimited chip-pulses, and the multipath distortion induced by the wireless channel are explicitly incorporated into the analysis. Several non-cooperative games are proposed wherein users may vary their transmit power and their uplink receiver in order to maximize their utility, which is denned here as the ratio of data throughput to transmit power. In particular, the case in which a linear multiuser detector is adopted at the receiver is considered first, and then, the more challenging case in which non-linear decision feedback multiuser detectors are employed is considered. The proposed games are shown to admit a unique Nash equilibrium point, while simulation results show the effectiveness of the proposed solutions, as well as that the use of a decision-feedback multiuser receiver brings remarkable performance improvements.","PeriodicalId":151241,"journal":{"name":"2007 41st Annual Conference on Information Sciences and Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129891281","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}

Tran","doi":"10.1109/CISS.2007.4298399","DOIUrl":"https://doi.org/10.1109/CISS.2007.4298399","url":null,"abstract":"In this paper, we study the rate-distortion performance of our two proposed multiplierless lifting-based IDCT approximations. The proposed IDCT approximations comprise of butterflies and dyadic-rational lifting steps that can be implemented using only shift and add operations, and allows the computational scalability with different accuracy-versus-complexity trade-offs. As rounding approximation leads to the truncation errors in the lifting steps, we estimate the worse-case truncation errors of our IDCT schemes as the distortion performance measurement. Because the cost of a hardware bit shift operation is negligible as compared with that of an addition operation, the overall rate cost is measured by the total minimal number of additions required to complete the IDCT multiplierless implementations. Through the rate and distortion analysis, we obtain the rate-distortion (RD) curves of 32-bit fixed-point implementations of our IDCT structures. From these RD curves, we present two complementary optimal solutions. The first optimal solution can pass IEEE-1180 test with the minimal number of additions. The second optimal solution can result in the finest IDCT approximations compared with the floating-type IDCT. Moreover, our RD analysis confirms that the solution proposed in (L. Liu and T.D. Tran, 2007) is RD-optimized and has a very good performance in terms of accuracy and complexity.","PeriodicalId":151241,"journal":{"name":"2007 41st Annual Conference on Information Sciences and Systems","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131105099","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 burden of demodulating the sensor data, and localizing the sensor which is communicating, falls on a network of collector nodes which are perpetually monitoring transmissions from the sensor network. This model allows the random deployment of very large numbers of sensor nodes with minimal capabilities, while shifting the complexity to a network of collector nodes. While the philosophy is similar to prior work on \"imaging\" sensor nets, the key difference is that the communication model is now sensor-driven, rather than collector-driven. The two major technical challenges addressed in this paper are as follows: (a) Are there simple physical layer implementations of the collector receiver for jointly solving the tasks of detection of a sensor transmission, estimation of the direction from which it comes, and demodulating the data? (b) Given that the collectors are not time synchronized well enough to permit the use of time-difference-of-arrival techniques for sensor localization, how well can the sensors be localized with spatial information alone, assuming that each collector node has a relatively small number of antennas? The results reported in this paper indicate that the preceding issues can be addressed satisfactorily with appropriate design of the collector physical layer, together with Bayesian combining of the spatial information extracted by each collector.","PeriodicalId":151241,"journal":{"name":"2007 41st Annual Conference on Information Sciences and Systems","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124372113","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}
