Multiple-Access Performance of Transmitted Reference UWB Communications with M-ary PPM
GLOBECOM 2008 - 2008 IEEE GLOBAL TELECOMMUNICATIONS CONFERENCE.
TL;DR:
To increase the data rate for transmitted reference (TR) ultra-wideband (UWB) systems, M-ary pulse position modulation (PPM) is used in this paper and a new method to derive the variance of the Gaussian random variable resulted from multiple-access interference (MAI) is developed using the power delay profile (PDP) of the channel.

Transmitted Reference Ultra-Wideband Communications with M-ary PPM
GLOBECOM 2008 - 2008 IEEE GLOBAL TELECOMMUNICATIONS CONFERENCE.
TL;DR:
Analysis and numerical results show that TR UWB systems with M-ary PPM using chip discrimination is robust against high-power interfering users in wireless networks where centralized power control is infeasible, such as ad-hoc networks.

2005 article
Threshold discrimination and blanking for large near-far power ratios in UWB networks
Lovelace, W. M., & Townsend, J. K. (2005, September). IEEE TRANSACTIONS ON COMMUNICATIONS, Vol. 53, pp. 1447–1450.
author keywords: impulse radio (IR); interference; networks; ultrawideband (UWB) radio
TL;DR:
It is found that even a small number of very near interferers can greatly reduce the performance of a system without blanking or discrimination, and a statistical model is developed that predicts bit-error performance for binary offset pulse position modulation as a function of near-far density and power for varying discrimination thresholds.

2002 journal article
The effects of timing jitter and tracking on the performance of impulse radio
IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, 20(9), 1646–1651.
author keywords: impulse radio (IR); medium access control (MAC) layer; network; timing jitter; tracking; ultra-wideband (UWB) radio; wireless
TL;DR:
The performance of IR is very sensitive to timing jitter and tracking, at least in part due to the very narrow pulses, and orthogonal 4-ary pulse position modulation out performs binary offset PPM at all jitter levels in thermal and pulse noise.

Efficient simulation of rare jitter probabilities in atm switches
TR (Center for Advanced Computing and Communication), (4).
TL;DR:
A novel importance sampling simulation methodology is presented to estimate the 1-Point CDV for CBR sources in the presence of background VBR traffic and it is observed from experimental results that the improvement in simulation efficiency is inversely proportional to the probability being estimated.
