“…This is possible because the interference is deterministic and not random. To further improve the BER performance of site diversity in a PB/MC-CDMA system, the proposed scheme introduces interference cancellation [16,17] into the STBC site diversity scheme. In interference cancellation, exact knowledge of the interfering bits is unknown, instead, estimates are used.…”

It has been proved that site diversity is an effective technique to improve the bit error rate (BER) performance for users located at the cell edge. In this paper, the downlink site diversity is applied to a partial block multicarrier-CDMA (PB/MC-CDMA) system, which is a newly proposed and more flexible system compared to the well-known multicarrier CDMA (MC-CDMA) system. We propose a space-time block coding with interference cancellation (STBC-IC) site diversity scheme, where the STBC is adopted on the site diversity participant base stations. A joint code assignment enables the mobile users to get full diversity and reduce inter-cell interference, whereas IC eliminates the intra-cell interference from the users that use the same partial block as the desired user. The BER performances using site diversity, STBC site diversity, and the proposed STBC-IC site diversity in PB system are evaluated by computer simulations. The results show that the site diversity technique works well in the PB system for users close to the cell edge. With the proposed STBC-IC site diversity scheme, we can expect satisfying BER and throughput results.

“…The advancement in wireless communications has led to an increasing demand for operating frequency bands which has made the radio spectrum congested and even standardized frequency band allocated systems overlap with each other [1][2][3][4]. Although the wide frequency range of ultrawideband (UWB) systems provides many advantages, it will cause interference to the existing wireless communication systems, such as the Cband systems at 3.7-4.2 GHz and wireless local area network (WLAN) for IEEE 802.11a operating in 5-6 GHz [3,5,6]. To overcome this problem, several novel planar microstrip antennas and filters with band notch characteristic have been presented recently [3,[5][6][7].…”

Light‐emitting diode‐based (LED) visible light communication (VLC) has become a candidate in next generation ultrahigh‐speed indoor wireless local area network. Within this scenario, it is most likely for a receiver to obtain the signals from multiple LED sources, which in general brings about interference among the transmitters and may result in failure detection. In this article, space‐time block coding (STBC), as a representative multiple antenna techniques, is adopted to enhance the VLC network performance for its effective suppression on the intertransmitter interference. We experimentally demonstrate a multiple input single output VLC network consisting of two RGB‐LEDs. Using STBC‐OFDM Coding, a total throughput of 500 Mb/s is achieved and the free space transmission reach can be extended as long as 5 m. As far as we know, it is the fastest speed and longest distance in multiple antenna VLC network using STBC coding. Both theoretical simulation and experimental investigation reveal great improvements in the robustness, flexibility, and compatibility of a LED‐VLC network due to the appropriate coding scheme. © 2015 Wiley Periodicals, Inc.
