Generalized Noncoherent Ultra-Wideband Receivers (2014)
Abstract / truncated to 115 words
This thesis investigates noncoherent multi-channel ultra-wideband receivers. Noncoherent ultra-wideband receivers promise low power consumption and low processing complexity as they, in contrast to coherent receiver architectures, relinquish the need of complex carrier frequency and phase recovering. Unfortunately, their peak data rate is limited by the delay spread of the multipath radio channel. Noncoherent multi-channel receivers can break this rate limit due to their capability to demodulate multi-carrier signals. Such receivers use an analog front-end to separate the received signals into their sub-channels. In this work, the modeling and optimization of realistic front-end components is addressed and their impact on the system performance of noncoherent multi-channel ultra-wideband receivers is analyzed. With a proposed generalized mathematical framework, ... toggle 12 keywordsUWB – noncoherent – multi-channel – MIMO – low-power – low-complexity – nonlinear – receiver – multiplier – integrator – mixed-signal – signal processing
