Non-coherent UWB receivers are often implemented using energy detection architectures which are very sensitive to noise in the channel and interference. Therefore, the receiver bandwidth plays an important role since the total noise and interference energy is proportional to this bandwidth. This work provides analytical expressions to find the optimal receiver bandwidth and quantifying the effect on the bit-error-rate (BER) due to channel noise and adjacent-channel interference (ACI). A reduction in receiver bandwidth beyond the optimal point is shown to have minimal impact on BER performance when ACI is negligible.

“…In [7], authors proposed a front end design in 0.18 µ CMOS technology that consumes 4.32 mW, whereas in a more recent paper the authors in [8] proposed a front end in 90 nm technology that consumes 3.6 mW when active. Authors in [9] have discussed power consumption of various wireless technology for WPAN applications. As mentioned, authors in [9] say that the power consumption of wireless devices scales with the data rate.…”

A low power adaptive digital baseband architecture is presented for a low-IF receiver of IEEE 802.15.4-2006. The digital section's sampling frequency and bit width are used as knobs to reduce the power under favorable signal and interference scenarios, thus recovering the design margins introduced to handle the worst case conditions. We show that in a 0.13 µm CMOS technology, for an adaptive digital baseband section of the receiver, power saving can be up to 85% (0.49 mW against 3.3 mW) in favorable interference and signal conditions. The proposed concepts in the design are tested using a receiver test setup where the design is hosted on a FPGA.

“…And the resulting LDC only approaches 1% [5,29]. As a consequence, the overall transceiver power consumption can be expected to keep below 1 mW, while providing a data rate of 10 Mbps with an acceptable QoS [30]. Although this incomparable energy-efficient transmission of UWB-IR, as indicated by most investigations [11,12,14], the receiver synchronization process as well as sophisticated correlation-based detection is generally energy-consumed in the presence of highly dispersive propagations, which may significantly offset the advantages of UWB based green transmissions.…”

In this article, we investigate a promising transmission approach for green communication networks. By combining the appealing single-cycle modulation technique with traditional pulse modulation found on the underlay communication philosophy, the presented ultra-spectra communication system can improve the energy efficiency significantly. In transceiver, the emission signal contains two parts, the information-bearing baseband waveform with an extremely short duration and the information-synchronized carrier component. Alternatively, without carrier signaling the intermittent emission can be adopted to further reduce its operational power. By optimally allocating the power in different bands, a water-filling emission spectrum inspired by a novel conception of radius basis function neural-network is proposed for maximizing transmission energy efficiency in the presence of external interference. In receiver, the carrier-synchronized signal greatly alleviates the power-consumed timing acquisition, and provides extremely precise synchronization for information detection in intensive multipath environments. In addition, from a pattern classification perspective, a low-complexity noncoherent detection scheme is suggested to enhance receiving performance and minimize energy consumption. Performance analysis demonstrated that the whole transmission scheme can indeed be realized within an ultra-low-power framework, which shows great advantages to traditional strategies.
