Texto completoThis thesis is devoted to the study of mutual contributions between games theory and informationtheory and their applications to decentralized communication networks. First, game theoryprovides answers to optimization problems in which agents interact. In a game, players chooseactions and obtains gains called utilities. Assumptions about the information possessed by playersbefore play is fundamental to determine the outcome a game, also called equilibrium. When thesame game is repeated from stage to stage and the players do not observe the past actions perfectly,then the equilibrium utilities are not known. On the other hand, information theory studiesthe performance of a communicating system. Nowadays, communication networks are so densethat they can not organize around a single central operator. Game theory is appropriate to explorenew organizations of communication networks in which decisions are taken locally. At first,in Chapter 3, we study the game of power control in terms of energy efficiency, thanks to theexisting results for repeated games. Transmitters are regarded as players and choose the transmissionpower of the signal, considered as their action. The objective of a player is to choose anoptimal power for the quality of its own communication. The players do not observe the pastactions perfectly, but we show that the observation of the "signal over interference plus noiseratio" is sufficient to ensure optimal equilibrium results for the communication network. In a secondstep, we use the tools of the information theory for further study of the flow of informationamong the players. In Chapter 4, an encoder sends an extra signal to the players so that theyperfectly observe the actions chosen in the previous stage-game. The observation of players issufficiently precise to characterize the set of equilibrium utilities of the repeated game. Theseresults are, in turn, used to model new communication networks and to provide more realisticsolutions. In Chapter 5, we deepen the study of equilibrium utilities when players observe thepast actions to through an arbitrary observation channel. We show a rate region is achievablefor the multi-user channel with states which includes an encoder, two legitimate receivers andan eavesdropper. This result allows us to study the correlations over the sequences of actions agroup of players can implement while keeping it secret from an opponent player. The study ofmulti-user channels is a step towards the characterization of equilibrium utilities in a repeatedgame with imperfect monitoring

Recently , CDMA(Code Division Multiple Access) System uses PCS(Power Control Scheme) including CLPC(Close Loop Power Control) and OLPC(Open Loop Power Control), so that it can perfectly compensate Path Loss, partially overcome Shadowing and Multi-Path Effect. The received signal become to P.C.E. (Power Control Error) signal which power is LogNormal Distribution Style with =1dB~4dB. In this thesis, the received signal will combine the other PCS including Antenna Diversity、Sectorization、Voice Activity Monitoring to improve System Capacity and we will also consider Non-Uniform User Distribution. Due to those factors on this model, we expect to establish a realistic model and to use & (Outage Probability) to evaluate the effect of System Capacity. According to the result of this thesis, we can get the conclusion as bellow: (I.)Under Uniform User Distribution 1. Voice Activity Monitoring and Overlap Angle will do a few effect of System Capacity. 2. System Capacity will get the direct proportion gain under using the Skills of Antenna Diversity, but Sectorization does not. 3. The quantity of Multi-Path and the amount of P.C.E. will do a lot effect of System Capacity. (II.)Under Non-Uniform User Distribution 1. Non-Uniform User Distribution will cut down System Capacity. 2. Outer Interference Factor will be decayed and result in promoting the number of System Users while increasing Path Loss Factor . 3. The quantity of Shadowing will do a few effect of System Capacity. 4. Adding an Antenna Diversity will enhance more System Capacity than adding a Sectoring Area. 5. Putting down the of P.C.E. will improve much more System Capacity than using the schemes of Antenna Diversity and Sectorization.

In this thesis, the system performance of an M-ary DS-CDMA system with antenna diversity array is investigated for coherent and noncoherent reception of uplink signals. In addition, the effect of imperfect power control resulting in a lognormal distribution of signal power on the system performance is also studied. Theoretical expressions for the bit error rate (BER) performance as a function of number of orthogonal signal set element M, number of active users, and branch of diversity are derived for different power control errors. For a prescribed BER, the system capacity in terms of number of active users that can be supported under imperfect power control is evaluated and compared for the coherent and noncoherent reception. The results show that the M-ary orthogonal modulation and diversity technique can offer great performance improvement, even under imperfect power control. However, the advantage of M-ary technology is almost lost due to bad power control, even increasing the number of orthogonal signal set element M. For a specified performance, the derived results can be used as guides in evaluating the required quality of power control for a DS-CDMA system with various scenarios, such as different number of orthogonal signal set element M, different branch of diversity, and coherent or noncoherent reception. Simulation results verify the theoretical derivations.

In this thesis, the performance of a direct sequence codeivision multiple access system with imperfect power controlperated over a multipath fading indoor radio channel isnalyzed. It has been suggested that DS-CDMA be used as aultiple access predetection diversity method and power controlo resist the effects of multipath fading and near-far problemor indoor radio channel. In practical, power control schemes not perfect and the degradation in performance will occurue to the imperfect power control. Therefore, we consider theffect of the performance of the DS-CDMA system impaired bymperfect power control, when receivers employ coherent BPSKemodulation or noncoherent DPSK demodulation for indoor radioommunication. The performance evaluations of these schemes haveeen made in our simulation and the performances of theredetection multipath diversity with channel coding impairedy imperfect power control are also investigated.
