“…Energy detector receiver is one suitable candidate due to its low complexity features. As pointed out, for example, in [2] and [3], the cost for achieving low complexity feature is generally a weaker detection performance. An advantage of the ED receiver, if compared to coherent receivers, is its tolerance against synchronization errors [15].…”

“…In PPM case, it is inevitable to receive two separate predefined time intervals of which one is "empty". [2] [3] Different approaches have been reported when evaluating the optimization of the ED receiver. The study in [17] has similarities to the research of this paper.…”

“…[1] The aforementioned modulation methods of the IR-UWB signaling have been studied, for example, in [2]- [4]. Based on a comparative analysis in [2] and [3], PSK advantage is high power efficiency, smooth spectrum and with M-ary PAM it is possible to achieve higher data rates. If bandwidth is not an issue, M-ary PPM has low spectral lines and dimensionality.…”

In this paper, we are evaluating the performances of energy detector receiver with on-off-keying (OOK) and pulse position modulation (PPM) in ultra wideband (UWB) communications. Energy detector (ED) receivers are considered as a lowcomplexity and low-power consumption option for the more complex coherent receivers. Obviously, the tradeoff for low complexity is degraded detection performance. A challenge of the energy detector receiver is to define an optimized integration time and with OOK, defining the optimal energy threshold for the decision of the received bit. Here, we define these variables using two different channel models for comparison purposes: the IEEE 802.15.6 channel model 3 and a real, measured hospital channel model. Performance of the energy detector receiver with two different modulation methods, OOK and PPM, is compared using the two aforementioned channel models. The system model is based on the IEEE 802.15.4-2011 standard UWB physical layer signal structure and a modified version of it, suggested earlier.

“…Note that the number of fingers also depends on the tradeoff between transfer signal parameters and receiver design [5]. Table 1 summarised the transmitter signal and channel parameters we used in LOS/ENLOS scenarios for all considered Rake receivers [21,22]. Other parameter values are kept identical to those in [7].…”

In this study, different pulse modulation parameters, such as symbol error rate (SER), power loss and bandwidth were investigated to highlight the most suitable parameter for narrowband interference cancellation in ultra-wide-band (UWB) Rake receivers. Thus, the performance of transmitter pulse was evaluated at the UWB Rake receiver. Finally, comparison of various filter bank receivers in terms of number of filters and SER was achieved by using a new accurate indoor UWB IEEE model channel with different propagation scenarios.

“…They have tremendous advantages over the previously used applications in these fields. UWBs provide high data rates, have higher channel capacity, more resistance to any interception or deception, and a much lower power consumption, thus making them more acceptable and their use more widespread [1]. Due to the inherent low-and high-frequency components of UWB short pulse signals, they are deemed appropriate for use in through wall imaging and ground-penetrating radar systems that need deep penetration and high-resolution images [2].…”

This study presents a novel compact high gain dual reflector antenna design with a switchable feeder for ultra‐wide band (UWB) applications. The design comprises a main parabola, a replaceable feeder antenna that is chosen depending on the requirements in a given situation, and an axially displaced elliptical sub‐reflector. The functioning of two different feeder antennas with manual switching option, the partly dielectric loaded K‐Vivaldi and double‐ridged horn (RH), is discussed in this research study. When the K‐Vivaldi is employed, the dual reflector antenna is more appropriate for impulse radiation with 33:1 operational bandwidth, ranging from 600 MHz to 20 GHz. The double‐RH feeder antenna displays more efficiency than the K‐Vivaldi one; however, the bandwidth in this case goes down to 12:1, ranging from 1.6 to 20 GHz. The sub‐reflector, situated inside the main parabola aperture with onset type of feeders, reduces the depth of the structure to 16 cm. The antenna dimensions are 60 cm × 60 cm x 16 cm. Experiments have shown that the designed antennas display good efficiency and high gain performances in UWB operations.
