Abstract-IR-UWB applications in indoor localization, to fill the gaps in the indoor high precision localization technology. IR-UWB has a high bandwidth, low power consumption and no carrier. The pulse signal can provide high time resolution, so it can get higher localization accuracy. In this paper, to locate by using TOA synergy AOA based on the IR-UWB signal. This localization algorithm, only need one anchor to complete it. In the case of multipoint localization, the tags distributed in the special position may cause some localization error in TOA. This will be resolved by combining with the AOA. Furthermore, we have tested on the HN-EVK1000 equipment.Index Terms-AOA, indoor localization, IR-UWB, TOA.

“…DESSERT uses a likelihood-based approach as in the recent work [18], [19]. However, DESSERT innovates in three different aspects: 1) detection is online, which greatly simplifies implementation and reduces memory requirements, 2) detection uses soft-decision, and 3) a postprocessing on the received signal is used to provide robustness against MUI.…”

Abstract-Energy-detection (ED) receivers can take advantage of the ranging and multipath resistance capabilities of impulseradio ultra-wideband (IR-UWB) physical layers at a much lower complexity than coherent receivers. However, ED receivers are extremely vulnerable to multi-user interference (MUI). Therefore, the design of IR-UWB ED architectures must take MUI into account. In this paper, we present the design and evaluation of two complementary algorithms for reliable and robust synchronization of IR-UWB ED receivers in the presence of MUI: 1) powerindependent detection and preamble code interference cancellation (PICNIC) and 2) detection of start-frame-delimiter through sequential ratio tests (DESSERT). PICNIC addresses packet detection and timing acquisition while DESSERT focuses on startframe-delimiter (SFD) detection. Both algorithms are evaluated with the IEEE 802.15.4a IR-UWB physical layer, standardized for low data-rate networks. The performance evaluation with extensive simulations show that our algorithms outperform nonrobust synchronization algorithms by up to two orders of magnitude in the presence of MUI.Index Terms-IEEE 802.15 standards, interference cancellation, multiple-access interference, ultra-wideband communication.
