Providing high data rate wireless transmissions has been difficult in indoor environments, particularly in multi-floor buildings. One way to achieve high data rate wireless transmissions is to reduce the radio transmission distance between the transmitter and the receiver by using distributed antenna systems (DASs) and employing frequency reuse. However, due to the reuse of the limited available spectrum,...
It is well known that providing high data rate wireless mobile services is a major challenge in indoor environments, particularly in multi-storey buildings. One way to achieve high data rate wireless transmissions is to reduce the radio transmission distance between the transmitter and the receiver by using distributed antenna systems (DASs) employing frequency reuse.

In this paper, the achievable rate of distributed antenna systems (DASs) in high buildings is investigated for indoor downlink high data rate wireless transmission. A DAS, where radio transmission/reception within one or several neighbouring floors is controlled by a central unit (CU) exploiting the entire system bandwidth is considered. The same frequency channels are reused by all the CUs, co-channel...
In this paper, the impact of co-channel interference on the achievable uplink spectral efficiency of an in-building wireless communication system employing DAS is examined. In the system, remote antenna units (RAUs) are deployed on each floor throughout the building and connected to a central unit (CU) where received signals are processed. System performance is investigated by using a propagation...

Performance of distributed antenna systems (DASs) is investigated for high data rates transmission in high buildings. Downlink transmission is considered, neighbouring floors are grouped together and controlled by a central unit (CU). The spectrum is not reused in the floors controlled by the same CU, however it can be reused among floors belonging to different CUs. Therefore, co-channel interference...

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...
