“…However, this transmitter cannot generate a pulse with a 3 dB bandwidth larger In table II, a qualitative comparison between the presented IR-UWB emitters is done. It appears that the transmitter presented in [23] is the best in terms of central frequency range, despite it has the highest energy consumption. More generally, the transmitters based on ring oscillators are the most interesting regarding the pulse central frequency range.…”

Ultra-WideBand Impulse Radio (IR-UWB) is a wireless communication technology well-suited for short range communications (about 10 meters) and has the advantage to allow real-time location with a precision of 5 cm. However, its use has been standardized in some standards and especially in the IEEE 802.15.4 dedicated to Wireless Personnal Area Network (WPAN) and in the IEEE 802.15.6 dedicated to Wireless Body Area Network (WBAN). After presenting requirements of each standard and a literature survey on the IR-UWB emitter, the design of a multi-standard IR-emitter based on the frequency transposition pulse synthesis is proposed in a 28 nm FD-SOI technology. The proposed design has been validated at the transistor level using electrical simulations which take into account the parasitic capacitance at each critical node of the circuit. Moreover, results show that the proposed circuit has the potential to be the first multi-standard IR-UWB emitter which covers every channel of the IEEE 802.15.4 and 802.15.6 standards.

“…Ultra-wideband (UWB) signals [ 7 ] can solve the multipath problems to be faced in these scenarios. UWB signals are widely used in low-power short-range wireless communication [ 8 ] due to their large bandwidth, low power consumption, and strong ability to distinguish multipath signals. The Saleh-Valenzuela (S-V) model [ 9 , 10 , 11 ] has been adopted as a UWB system channel model for small-scale fading.…”

Low-Complexity Joint Angle of Arrival and Time of Arrival Estimation of Multipath Signal in UWB System

In an ultra-wideband (UWB) system, the two-dimensional (2D) multiple signal classification (MUSIC) algorithms based on high-precision 2D spectral peak search can jointly estimate the time of arrival (TOA) and angle of arrival (AOA). However, the computational complexity of 2D-MUSIC is very high, and the corresponding data model is only based on the dual antennas. To solve these problems, a low-complexity algorithm for joint AOA and TOA estimation of the multipath ultra-wideband signal is proposed. Firstly, the dual antenna sensing data model is extended to the antenna array case. Then, based on the array-sensing data model, the proposed algorithm transforms the 2D spectral peak search of 2D-MUSIC into a secondary optimization problem to extract the estimation of AOA via only 1D search. Finally, the acquired AOA estimations are brought back, and the TOA estimations are also obtained through a 1D search. Moreover, in the case of an unknown transmitted signal waveform, the proposed method can still distinguish the main path signal based on the time difference of arrival of different paths, which shows wider applications. The simulation results show that the proposed algorithm outperforms the Root-MUSIC algorithm and the estimation of signal parameters using the rotational invariance techniques (ESPRIT) algorithm, and keeps the same estimation accuracy but with greatly reduced computational complexity compared to the 2D-MUSIC algorithm.

The commonly used method is connecting a bypass low-noise amplifier (LNA) to the receiving chain or a power amplifier (PA) to transmitting path alone.…”

In this letter, a 4.5-7.5 GHz highly integrated transceiver front-end, incorporating two single-pole three-throw (SP3T) transmit/receive (T/R) switches, a low-noise amplifier (LNA), a power amplifier (PA), and a bypass path for UWB positioning and communication systems applications, is reported. The mode switches among transmitting, receiving, and bypass are achieved by utilizing two control voltages through integrating a 2-4 decoder. Meanwhile, to ensure low-power dissipation in different modes, the LNA and PA work in different modes (enable or disable) for transmitting and receiving status while both the LNA and PA are disabled for bypass mode. Fabricated by using 0.5-μm GaAs pHEMT process, the presented FEM achieves 20-dB gain, and 2.5-dB typical noise figure for receiving mode, 8-dB gain, and 16-dBm OP1dB for transmitting mode, and 1.8 dB insertion loss for bypass mode, with a compact chip area of 1.5 mm × 1.7 mm. To the best of authors' knowledge, the presented circuits are the highest integrated and smallest chip area transceiver front-end for UWB application among all previously reported UWB-related RF front-end chips.
