“…However, the IR-UWB, featuring a narrow duration pulse width, has two equal applications, which cannot be replaced by the narrowband communication. The first one is energy-efficient high data rate communication [25][26][27][28][29] . As shown in Table 2, the narrowband communication systems, such as BLE and WiFi, can only achieve a low or medium data rate.…”

The Ultra-WideBand (UWB) technique, which offers good energy efficiency, flexible data rate, and high ranging accuracy, has recently been recognized as a revived wireless technology for short distance communication.This paper presents a brief overview of two UWB techniques, covering Impulse-Radio UWB (IR-UWB) and Frequency-Modulation UWB (FM-UWB) methods. The link margin enhancement technique, Very-WideBand (VWB), and power consumption reducing technique, chirp UWB, are also introduced. Then, several potential applications of IR-UWB with transceiver architectures are addressed, including high data rate proximity communication and secure wireless connectivity. With fine-ranging and energy-efficient communication features, the UWB wireless technology is highly promising for secure mobile Internet of Things (IoT) applications.

“…In addition, the system only recognizes the signal from the nearest target using a leading-edge detection method because it focuses on hand gesture recognition. The leading-edge detection method detects only the first arriving signal and ignores the following signals [18]. The start times of the fast and slow clocks are determined based on the timing calculator when considering the timing gap measured by the TDC and the wake-up time.…”

This article introduces a time-domain-based artificial intelligence (AI) radar system for gesture recognition using 33-GS/s direct sampling technique. High-speed sampling using a time-extension method allows AI learning to be applied to a time-domain radar signal reflecting information on both dynamic and static gestures, and thus can recognize not only dynamic but also static gestures. The Vernier clock generators and high-speed active samplers applied with the time-extension technique makes sampling at 33 GS/s possible. A 1-D convolutional neural network and long short-term memory are employed for both static and dynamic gestures and recognition rates of 93.2% and 90.5% are obtained, respectively. The radar system is implemented using a 65-nm CMOS process with a power consumption of 95 mW.

“…Following the regulation of the Federal Communication Commission (FCC) approved in 2002, UWB devices are authorized to operate over the [3.1-10.6] GHz frequency band within a power limit of -41.3 dBm/MHz, to maintain a safe coexistence with other radio services [12][13][14]. A particular UWB approach is the Impulse Radio (IR) baseband scheme, which relies on transmitting data symbols via repetitive pulse signaling, and is characterized by an appealing low-cost transceiver architecture [15][16][17][18][19][20]. Due to the stringent power and spectral constraints of regulatory bodies, a highly efficient IR transmission is needed, while the utilized pulses play an essential role in determining the power efficiency of the modulated signal [21].…”

“…Digitizing the generation system provides a very high flexibility in the pulse design, however, it is the most expensive approach, especially when dealing with GHz-signals. Incorporating a local oscillator to shift the spectrum towards the desired band, significantly increases the level of complicacy, and hence, pure impulse radio schemes have been considered as a good choice for simple and cheap UWB transceivers [16,18,23]. In this study, we investigate the design of carrier-free UWB generation using a few number of elementary pulses, so as to synthesize the transmitted signal at acceptable order of complexity and fit the low-cost IR systems demand.…”

Pulse design is critical for impulse radio communications, as it determines the transmission efficiency with respect to regulation spectral limits. In this paper, we propose the design of several novel pulse shapes relying on combinations of Gaussian derivatives with the target of improving the spectral efficiency. A general model for maximizing the efficiency of dual and triplet couplings is presented, employing the interior point global optimization algorithm. Then, the spectrum peak frequency is derived in closed form for any combination of two Gaussians with consecutive orders of derivation. The parameters controlling the time properties of the generated waveforms have been adequately adjusted to reach the best compliance with the spectral mask. Novel pulses have been investigated providing a high efficiency using simple generation mechanisms, which can be practically implemented via analog circuits. Results demonstrated the advantage of the proposed pulse shapes in terms of the bit error rate performance for 2 Gbps OOK and 1 Gbps PPM in AWGN and multipath channels.
