This thesis concerns two interference management methods, the power control and the smart antenna. Power control balances received powers of all users so that a measure of the co-channel interference achieves a minimum. Using the beamforming in the mobile communication system one can exploit the spatial structure of the interference to reduce it. For power(More)
—In this study we aim to assess the optimal successive group decoder (OSGD) considering different scenarios and in a wide range of testing metrics. We investigate the OSGD in the K−user interference channel (IC) and evaluate its capability to mitigate interference. We inspect OSGD performance in terms of its (ergodic and effective) capacity. Also, we(More)
— In modern greenhouses, several measurement points are required to trace down the local climate parameters in different parts of the big greenhouse to make the greenhouse automation system work properly. Cabling would make the measurement system expensive and vulnerable. Moreover, the cabled measurement points are difficult to relocate once they are(More)
— This paper investigates optical power control to enhance capacity of optical CDMA star coupled networks. We consider a network in which the nodes encode their optical signal by prime codes, and the resulting error rate performance is inspected with and without power control. Network impairments, such as fiber attenuation, star coupler loss, thermal noise(More)
—In this paper, we study the maximum stable through-put region of the proposed systems using stochastic dominance technique for optimizing utilization of a cognitive shared channel. A cognitive protocol on the general multipacket reception channel model is adopted [1], [2], where the primary transmission may succeed even in the presence of secondary(More)
