A New, Near-Coherent Detector Configuration for UWB Impulse Radio
نویسندگان
چکیده
Abstract—Since radio channels available have been assigned to traditional narrowband communication systems the only solution to establish new radio communication links is the frequency reuse. This has to be achieved without causing interference in the conventional radio systems. Ultra WideBand (UWB) radio uses extremely wideband wavelets to decrease the Power Spectral Density (psd) of radiated signal. In this paper a new demodulation technique called near-coherent demodulation is proposed for UWB systems. Closed form expressions are derived for the Bit Error Rate (BER) of the new demodulator. Results of simulations validate the derived theoretical BER performance of nearcoherent detection.

Uwb Impulse Radio with Gated Treshold Compensated Ppm Receiver
General agreement has been reached recently, that the coherent optimum receivers known from the theory of conventional communication systems are not feasible to implement low-cost and robust UltraWideBand (UWB) Impulse Radio (IR) receivers, especially if they have to offer an extremely low power consumption. Instead, Energy Detector (ED)-based noncoherent receivers have to be used [1]. Unfortun...
متن کاملNoncoherent Uwb Impulse Radio and Fm-dcsk: What Makes Them Different
For lack of empty radio bands, ultrawideband (UWB) radio system allowing reuse of already occupied frequency bands is the only solution to accommodate new wireless data communication services. Two types of UWB carriers are considered here, the frequency-shifted Gaussian pulse and chaotic signal with FM-DCSK modulation. A generalized model of transmitted reference systems is introduced first tha...
متن کاملEXIT chart aided design of near-capacity UWB impulse radio using self-concatenated codes
A near-capacity Time Hopping (TH) Pulse Position Modulation (PPM) based Ultra Wide Band (UWB) Impulse Radio (IR) system is proposed, which invokes iteratively detected Self-Concatenated Convolutional Codes (SeCCC) employing Extrinsic Information Transfer (EXIT) charts. The TH-PPM-UWB-IR-SeCCC system configuration is capable of operating within about 0.9 dB of the informationtheoretic limits.
متن کاملImpulse Wavelet versus Chaotic Carrier: Selection of Optimum Carrier for Uwb Radio
Data communications is going to wireless everywhere, from computer keyboard to Internet, from sensor networks to embedded systems. The spread of wireless communications is blocked by the fact that the radio channels have been already assigned to conventional communication systems and except a very few and crowded ISM bands there are no empty channels. Radio communications via channels already o...

This paper presents the performance of single band impulse radio systems, TH-UWB and DS-UWB, multiband impulse radio systems, MB-UWB, and multiband OFDM systems on the IEEE 802.15 UWB channel models CM1–CM4. The investigated impulse radio systems use approximately the spectrum 3–6 GHz and have a data rate around 100 Mbps. The DS-UWB system with a fractionally spaced Rake receiver with 10 finger...
