Information-theoretic Capacity Analysis in MIMO Distributed Antenna Systems

Distributed antenna system (DAS) can reduce the access distance and so lower the required transmit power compared with the conventional multiple input multiple out (MIMO) system. This paper investigated the information-theoretic capacity of DAS based on the channel model considering path loss, log-normal shadowing fading and Rayleigh fading. We find that the location of the receiver affects the...

Distributed Antenna Systems and MIMO Technology

With the explosive growth in wireless usage due in part to smart phones, tablet computers and a growing applications developer base, wireless operators are constantly looking for ways to increase the spectral efficiency of their networks. Multiple input/ multiple output (MIMO) technology, which made its first broad commercial appearance in 802.11n systems, is now gaining substantial momentum in...

Channel Capacity of Distributed Antenna System Using Maximal Ratio Transmission

In mobile communication systems, the received signal power varies due to fading, shadowing and path loss, resulting in the transmission performance degradation. Transmit antenna diversity is a promising technique to improve the transmission performance. For the downlink transmission, the outage probability in a service area can be improved by distributing the transmit antennas over the service ...

Downlink System Capacity Analysis in Distributed Antenna Systems

This paper focuses on the downlink system capacity in distributed antenna systems (DAS). Due to the complexity of actual wireless environments, a composite channel model is established which takes into account three factors, i.e., path loss, lognormal shadowing and Rayleigh fading. Based on the channel model, the probability density function (PDF) of the output signal-to-noise ratio (SNR) is de...
