A new microwave receiver configuration which transmits reference pulses embedded in data streams for synchronization is analyzed with a 90-nm IBM CMOS standard. A two-stage cascode low-noise amplifier (LNA) is proposed for the receiver front-end which is matched by a passive network to save on power-expensive matching techniques. The amplifier exploits a double-differential topology and achieves a below 4 dB noise figure near the center frequency. The overall 3-dB bandwidth is 3.3 GHz with peaking up to 20.5 dB in the -band. The back-end of the receiver is implemented through an adjustable analog window-detection circuit. It avoids the use of control voltage generators and sample-hold (S/H) blocks to save electronic overhead and is simulated with a 0.1~2.0 Gbps pulse stream. The achieved speed-to-power ratio for the back-end has a maximum limit of 266 GHz/W. When compared against simulated results of published literature, the proposed designs show improved performance in terms of small-signal gain, noise, speed, and power dissipation.

“…A pioneering work in studying multiuser detection techniques for DD-based PUD systems in found from (Varanasi, 1993). Other recent work on studying and analysing multiuser techniques with DD can be found from (Dang & van der Veen, 2007). Although multiuser DD schemes have been a more popular research topic, recently multiuser approaches have also been applied to ED (Xu & Brandt-Pearce, 2006).…”

“…For this reason, in this paper we propose a code design that can cancel out statistically, i.e., on average, the NBI in a multi-tone scenario. Accordingly, from (23) and (24) the conditions for code design in (28) on top of the previous page can be obtained, where C 1 is the same as in (27). Furthermore, we note that for those system setups where the framework in Section IV-A is inaccurate, the condition C 1 in (28) should be replaced by a similar optimization criterion that could be obtained from (26).…”

In this paper, we analyze the performance of a particular class of Transmitted-Reference (TR) receivers for Impulse Radio (IR-) Ultra Wide Band (UWB) communication systems, which is called Chip-Time Differential Transmitted-Reference (Tc-DTR). The analysis aims at investigating the robustness of this receiver to single-and multi-tone Narrow-Band Interference (NBI), and at comparing its performance with other non-coherent receivers proposed in the literature. It is shown that the Tc-DTR scheme provides more degrees of freedom for performance optimization, and it is inherently more robust to NBI than other non-coherent receivers. More specifically, it is analytically proved that the performance improvement is due to the chip-time level differential encoding/decoding of the Direct Sequence (DS) code, and to an adequate design of DS code and average pulse repetition time. The analysis encompasses performance metrics that are useful for both data detection (i.e., Average Bit Error Probability, ABEP) and timing acquisition (i.e., False Alarm Probability, P fa , and Detection Probability, P d). Moving from the proposed semi-analytical framework, the optimal code design and system parameters are derived, and it is highlighted that the same optimization criterion can be applied to all performance metrics considered in this paper. Also, analytical frameworks and theoretical findings are substantiated via Monte Carlo simulations.
