Coordinated multi-point (CoMP) is a very promising transmission scheme since it permits interference reduction and cell-edge throughput improvement. In this work, we study the performance of the joint processing multiple antenna multipoint cooperation using the maximum ratio transmission (MRT) technique. A closed form expression of the outage probability is(More)
In this paper we propose an analytical evaluation of the performance of the zero forcing precoding technique in terms of outage probability in a multicellular multiuser context. The channel model includes path loss shadowing and Rayleigh flat fading. Two cases are examined. The first one considers a constant lognormal shadowing. In this case, a closed form(More)
In this paper we study the performance of two downlink multi-cellular systems: a Multiple Inputs Single Output (MISO) system using the Alamouti code and a Multiple Inputs Multiple Outputs (MIMO) system using the Alamouti code at the transmitter side and a Maximum Ratio Combining (MRC) as a receiver, in terms of outage probability. The channel model includes(More)
The overall relay channel from the source to the destination via relays has temporal properties quite different from any cellular channel. This work presents a study for time-dependent performance of relay channels for both fast-fading and log-normal shadow fading in terms of average outage duration, frequency of outage and probability of outage. Results(More)
The implementation of cellular systems have aroused issues related to the design of cellular networks termed to as network dimensioning. It includes the coverage estimation and the traffic analysis. Simple models and methods are required to reduce the time consumption of these two analysis. At the same time, the growing demand for higher data rates(More)
