Recently, femtocell has been proposed as a good solution to increase the coverage area and capacity of the wireless communication system as well as meet the increasing demand for high data rate. The femtocell is low-cost, low-power and can be realized by deploying a femto-base-station connected to the core network via a wired-backhaul. Since the femtocell reuses the macrocell spectrum, co-channel...
In wireless systems, coverage and capacity is a major challenge especially in high buildings. The system performance is impaired by cochannel interference created due to the need to reuse the limited available spectrum in nearby floors. Each base station (BS) does not only receives signals from the desired user but also from cochannel interferers in the neighbouring floors, thereby limiting the coverage...
