Digital Receiver Design for Transmitted Reference Ultra-Wideband Systems

Digital Receiver Design for Transmitted Reference Ultra-Wideband Systems

A complete detection, channel estimation, synchronization, and equalization scheme for a transmitted reference (TR) ultrawideband (UWB) system is proposed in this paper. The scheme is based on a data model which admits a moderate data rate and takes both the interframe interference (IFI) and the intersymbol interference (ISI) into consideration. Moreover, the bias caused by the interpulse inter...

Optimal and suboptimal receivers for ultra-wideband transmitted reference systems

The optimal receiver for an ultra-wideband transmitted reference (UWB TR) system in a single user multipath environment is derived, based on knowledge of channel properties. The performances of this optimal receiver and other crosscorrelation receivers are analyzed and compared. The usual crosscorrelation receiver which is often used in UWB TR systems is shown to be suboptimal. In addition, an ...

Optimal Receiver Scheme for Transmitted-Reference Ultra-Wideband System in Coal Mine

— An average Transmitted-Reference (TR) receiver scheme based on orthogonal codes is proposed for improving the bit error rate (BER) performance and the transmitting rate of Ultra-wideband (UWB) TR receiver systems in coal mine. Orthogonal codes are used for modulating the reference pulses and the data pulses in each frame of every bit. Since the orthogonality of the two codes, the inter-pulse...

Noncoherent receiver designs for ultra-wideband systems

Self-Reference Ultra-Wideband Systems

In practical Ultra-Wideband (UWB) systems, Rake receivers are not able to fully take advantage of all resolvable paths, because of the required computational and power resources. On the other hand, Transmitted Reference (TR) schemes are simple, robust structures with low power consumption and they do not require channel estimation, but they sustain a 3dB energy/rate loss, as each symbol require...
