Channel Capacity of Distributed Antenna Network Using Transmit/Receive Diversity in a Multi-cell Environment

چکیده
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

A Study on Frequency Efficiencies of Distributed Antenna Network in Cellular System
Abstract In mobile communication systems, the received signal level varies due to fading, shadowing and path loss and therefore, the transmission performance degrades. Instead of using all of transmit antennas at one position, the outage probability in a service area can be improved by distributed antenna network (DAN) in which transmit antennas are distributed over the service area to transmit...
متن کاملMultiple-input multiple-output wireless communication systems using antenna pattern diversity
Multiple-input multiple-output (MIMO) wireless communication systems employ multiple transmit and multiple receive antennas to obtain significant improvement in channel capacity. However, the capacity is limited by the correlation of subchannels in non-ideal scattering environments. In this paper, we investigate MIMO systems that use antennas with dissimilar radiation patterns to introduce deco...

In this paper, joint water filling and maximal ratio transmission (joint WF-MRT) downlink transmit diversity for a single-carrier distributed antenna network (SC DAN) is proposed. The joint WF-MRT transmit weight allocates the transmit power in both transmit antenna dimension and frequency dimension, i.e., the power allocation is done both across frequencies based on WF theorem and across trans...
