Resource Allocation in Wireless Systems,me-varying nature of the wireless channel are essential. Two of the main resource management functions in a CDMA system are power control and rate allocation. This chapter presents a unified approach for power distribution and allocation in a multirate wideband CDMA system. Adaptive schemes to perfo

Iterative receivers and their graphical models,plementation has led to an interest in iterative receivers. This chapter introduces iterative receiver algorithms based on their graphical models. These consist of representing the factorization of a function of several variables into a product of functions of a lower number of variables. Using this

Fundamentals of Multi-User MIMO Communications,tical and practical issues associated with multiple-input multiple-output wireless channels. This activity was first focused primarily on single-user communications but more recently there has been extensive work on multi-user settings. The aim of this chapter is to provide an overview of the fundam

Collaborative Beamforming,remote receiver. The fluctuation of the SNR can be caused by several phenomena such as path loss, shadowing, and multipath fading . Beamforming is one of the techniques that can cope with this problem. Suppose that the transmitter is equipped with multiple antennas. If the same signal is transmi

Interference Rejection and Management,e encountered among cooperating systems, for example, the self-interference that is encountered in cognitive radio systems and ultra-wideband (UWB) communication systems. Both single-carrier, direct sequence signals and multicarrier signals are considered, and the effects of the interference on the

Cognitive Radio: From Theory to Practical Network Engineering,ss applications, is driving the development of new spectrum allocation policies for wireless communications. These new spectrum allocation policies, which will allow unlicensed users (i.e., secondary users) to access the radio spectrum when it is not occupied by licensed users (i.e., primary users)

Coded Bidirectional Relaying in Wireless Networks,relaying or, more general, multi-way relaying leverage on two conceptual blocks. The . is the shared nature of the wireless communication medium. On the one hand, this implies that there is interference when multiple transmissions are occurring simultaneously. On the other hand, the . in a sense tha
