In this paper, we propose an analysis of the joint impact of path-loss, shadowing and fast fading on cellular networks. Two analytical methods are developed to express the outage probability. The first one based on the Fenton–Wilkinson approach, approximates a sum of log-normal random variables by a log-normal random variable and approximates fast fading(More)
—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 multi-point cooperation using the maximum ratio transmission (MRT) technique. A closed form expression of the outage probability(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)
