A Study on Channel Capacity of Distributed Antenna Network Using Transmit/Receive Diversity in A Multi-Cell Environment

Distributed antenna network (DAN) is a promising wireless network which can mitigate the impacts of distancedependent/shadowing losses and fading. Frequency-domain space-time block coded-joint transmit/receive diversity (FDSTBC-JTRD) is an antenna diversity technique which allows an arbitrary number of transmit antennas while keeping the coding rate constant and is suitable for the downlink transmission. It obtains the frequency-diversity gain by exploiting the frequencyselective fading channel and improves the signal-to-interference plus noise power ratio (SINR) in a multi-cell environment. In this paper, we evaluate the channel capacity distribution of downlink single-carrier (SC-) DAN using FD-STBC-JTRD in a multi-cell environment. It is shown that multi-cell SC-DAN using FDSTBC-JTRD can allow the single-frequency reuse. Keywords; channel capacity, distributed antenna network, antenna diversity, transmit frequency-domain equalization, cochannel interference
