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...

Design Verification and Performance Evaluation of an Enhanced Wideband CDMA Receiver Using Channel Measurements

The spatio-temporal array receiver (STAR) decomposes generic wideband CDMA channel responses across various parameter dimensions (e.g., time delays, multipath components, etc.) and extracts the associated time-varying parameters (i.e., analysis) before reconstructing the channel (i.e., synthesis) with increased accuracy. This work verifies the channel analysis/synthesis design of STAR by illust...

Wideband Modem Design Using FPGAs

1. ABSTRACT New waveform requirements are pushing the limits of traditional modem design techniques. Fortunately, modern Digital-to-Analog Converter (DAC) and Analog-to-Digital Converter (ADC) can achieve sampling rates in the GHz range. These new DACs and ADCs allow designers to directly synthesize channels that have bandwidths of more than 500 MHz+; allowing either wideband or multi-channel m...

Performance of ultra-wideband correlator receiver using Gaussian monocycles

This paper investigates the performance of UltraWideband (UWB) correlator receivers for Gaussian monocycles under the condition of equal mean power and provides constructive reference to the selection of pulses. Several channel situations are examined including ideal single user AWGN channel, non-ideal synchronous, multipath fading and multiple access interference. Both numerical and analytical...
