Ultra Wideband Impulse Radio Systems with Multiple Pulse Types
Sinan Gezici, Zafer Sahinoglu, Hisashi Kobayashi +1
In an ultra wideband (UWB) impulse radio (IR) system, a number of pulses, each transmitted in an interval called a "frame", is employed to represent one information symbol. Convent…
A Two-Step Time of Arrival Estimation Algorithm for Impulse Radio Ultra Wideband Systems
Sinan Gezici, Zafer Sahinoglu, Andreas F. Molisch +2
High time resolution of ultra wideband (UWB) signals facilitates very precise positioning capabilities based on time-of-arrival (TOA) measurements. Although the theoretical lower b…
A Genetic Algorithm Based Finger Selection Scheme for UWB MMSE Rake Receivers
Sinan Gezici, Mung Chiang, H. Vincent Poor +1
Due to a large number of multipath components in a typical ultra wideband (UWB) system, selective Rake (SRake) receivers, which combine energy from a subset of multipath components…
Impulse Radio Systems with Multiple Types of Ultra-Wideband Pulses
Sinan Gezici, Zafer Sahinoglu, Hisashi Kobayashi +1
Spectral properties and performance of multi-pulse impulse radio ultra-wideband systems with pulse-based polarity randomization are analyzed. Instead of a single type of pulse tran…
Optimal and Suboptimal Finger Selection Algorithms for MMSE Rake Receivers in Impulse Radio Ultra-Wideband Systems
Sinan Gezici, Mung Chiang, H. Vincent Poor +1
Convex relaxations of the optimal finger selection algorithm are proposed for a minimum mean square error (MMSE) Rake receiver in an impulse radio ultra-wideband system. First, the…
Performance Evaluation of Impulse Radio UWB Systems with Pulse-Based Polarity Randomization
Sinan Gezici, Hisashi Kobayashi, H. Vincent Poor +1
In this paper, the performance of a binary phase shift keyed random time-hopping impulse radio system with pulse-based polarity randomization is analyzed. Transmission over frequen…
