“…Since different antennas are located at different positions, DAN can exploit the random variations in the shadowing and path losses. The recent advances in FDE and DAN for the broadband SC signal transmissions are introduced in [11]. To realize the high quality broadband SC signal transmissions, there are two crucial issues to overcome: the channel frequency-selectivity and the power loss due to the shadowing and distance dependant path losses.…”

In recent years, single-carrier system has again become an interesting and complementary alternative to multi-carrier system such as orthogonal frequency division multiplexing (OFDM). This has been largely due to the use of frequency domain equalizer implemented by means of fast Fourier transforms (FFT), bringing the complexity close to that of OFDM. This paper aims at providing an overview of single-carrier frequency domain equalization (SC-FDE) and its Wireless applications. We review the brief history and system model of SC-FDE, and the integration of SC-FDE and other wireless transmission techniques. We also present several possible future research topics about SC-FDE.

“…Compared to the time domain equalization techniques, the frequency domain equalization (FDE) has much less complexity which is not a function of the channel frequency selectivity. On the other hand, the data transmission between the mobile user and the base station (BS) suffers from the interference from the in-cell users as well as the co-channel interference (CCI) [3] (the in-cell interference and CCI together is called multi-access interference (MAI)). In our previous study [4], we have proposed a single-carrier frequency domain adaptive antenna array (SC-FDAAA) algorithm for the uplink transmission for conventional cellular systems.…”

In our previous study, we proposed a single-carrier frequency domain adaptive antenna array (SC-FDAAA) for the conventional cellular network. It has been proved that the SC-FDAAA can effectively suppress the interfering signals from other users in a severely frequency selective fading channel. In this paper, we study the SC-FDAAA for distributed antenna network (DAN) and two DAN SC-FDAAA schemes are proposed. They are, namely, distributed SC-FDAAA and unified SC-FDAAA. The performances of the two DAN SC-FDAAA schemes are compared by computer simulations and the results show that the unified SC-FDAAA has better bit error rate (BER) performance.

“…To solve the high PAPR problem, conventional single-carrier (SC) transmission, again, attracted much interest. Recently, the combination of SC-FDE and frequency division multiple access (called SC-FDMA) [5] has been considered as a more suitable solution for the uplink (from mobile users to BS) transmission. On the other hand, to save the bandwidth usage, the same carrier frequency/frequencies may be reused by neighboring cells to increase the bandwidth efficiency.…”

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.
