“…4. It is shown that DAN SC-FDAAA can successfully cancel the MAI, and the average BER performance improves as the FRF increases, as already been proved in [5]. Since we are considering an un-coded system, a target average BER of 10 -2 is used, which is marked by the dotted red line in Fig.…”

Abstract-In our previous study, we proposed a single-carrier frequency domain adaptive antenna array (SC-FDAAA) algorithm for the distributed antenna network (DAN). It has been proved that SC-FDAAA can effectively suppress the interfering signals from other users in a severely frequency selective fading channel. In this paper, we studied the capacity performance of DAN SC-FDAAA. Both the ergodic capacity and outage capacity given by the maximum number of users are evaluated.

The target data rate for the next generation wireless communication network will be around Gbps. To realize such a high data rate transmission, broadband transmission has been used in the current wireless communication network and it is also going to be employed by the next generation network. Due to the multi-path fading with large delay spread, broadband wireless channel is characterized by severe frequency selectivity [ ]. "s a result, it is necessary to suppress the inter-symbol interference ISI at the receiver. The ISI can be suppressed by time domain equalization techniques such as maximum likelihood sequence estimation MLSE [ ]. However, when the data rate increases, the number of resolvable propagation paths increases as well and hence, the complexity of MLSE grows exponentially to the number of paths. Fortunately, the ISI problem can be solved by introducing frequency domain equalization FDE [ ] at the receiver. It is well known that the frequency selectivity problem can be solved by the use of multi-carrier transmission technique such as orthogonal frequency division multiple access OFDM" [ ] for the downlink from base station "S to mobile users transmission. However, the multicarrier transceivers are suffering from high peak-to-average power ratio P"PR problem which can lead to severe performance degradation. To solve the high P"PR problem, conventional single-carrier SC transmission, again, attracted much interest. Recently, the combination of SC-FDE and frequency division multiple access called SC-FDM" [ ] has been considered as a more suitable solution for the uplink from mobile users to "S transmission. On the other hand, in order to save the bandwidth usage, the same carrier frequency/frequencies may be reused by neighboring cells to increase the bandwidth efficiency. "s a result, co-channel interference CCI [ ] becomes the dominant performance limitation instead of the thermal noise. In addition, multi-user interference MUI

Single-carrier frequency domain adaptive antenna array (SC-FDAAA) has been proposed and proved in our previous study to be effective in suppressing multiple access interference in a severely frequency selective fading channel. In this paper, we studied the performance of SC-FDAAA in a distributed antenna network (DAN). To make it clear whether the performance of SC-FDAAA can benefit from the distributed nature of DAN or not, we made a comparison between DAN and the traditional cellular network, that is, central antenna network. The bit error rate distribution and the system capacity (both link capacity and cellular link capacity) are presented. It is shown that by using the SC-FDAAA, cellular link capacity is maximized by using single frequency reuse. In addition, the capacity of SC-FDAAA can also benefit from the distributed nature of DAN.
