An interference cancellation receiver that exploits the unique characteristics of single-carrier frequency-division multiple access based systems is proposed and results indicate that proposed methods work particularly well for low overlap ratios compared to interference coordination and no cancellation schemes.

Fundamental limits and improved algorithms for linear least-squares wireless position estimation
Wireless Communications and Mobile Computing, 12(12), 1037–1052.
author keywords: wireless positioning; time-of-arrival (TOA); least-squares (LS) estimation; maximum likelihood (ML); Cramer-Rao lower bound (CRLB)
TL;DR:
T theoretical lower bounds on performance of linear least-Squares (LLS) position estimators are obtained, and performance differences between LLS and nonlinear least-squares (NLS) position estimationators are quantified.

An iterative interference cancellation method for co-channel multicarrier and narrowband systems
Physical Communication, 4(1), 13–25.
author keywords: CDMA; Co-channel interference; Femtocell; NBI; OFDMA; Successive interference cancellation
TL;DR:
Through computer simulations, it is shown that the proposed CCI cancellation method has lower complexity compared to joint demodulation, and it yields significant gains in the symbol error rate (SER) performance of both the NB and multicarrier systems.

Searchback Algorithms for TOA Estimation in Non-coherent Low-rate IR-UWB Systems
Wireless Personal Communications, 48(4), 585–603.
author keywords: Ranging; Non-coherent; Sub-Nyquist sampling; UWB; First path detection; Energy detector
TL;DR:
Simulation results show that JBSF typically performs better than SBS if the inter-cluster delay parameter (K) is not selected appropriately for SBS, and even at sampling rates much smaller than the Nyquist rate, ranging accuracies can be obtained using a non-coherent UWB receiver.

A review on multiple access interference cancellation and avoidance for IR-UWB
Signal Processing, 87(4), 623–653.
author keywords: multiuser interference cancellation; ML; MMSE; review; tutorial; ultrawideband
TL;DR:
A comprehensive review of multiple access interference (MAI) avoidance/cancellation for impulse radio (IR) ultrawideband (UWB) systems is presented, to outline analogies and differences between IR-UWB and DS-CDMA approaches to handle the MAI, and to identify possible research directions.

Adaptation of two types of processing gains for UWB impulse radio wireless sensor networks
IET Communications, 1(6), 1280.
TL;DR:
An adaptive assignment scheme for two types of multiple- access parameters in cluster-based wireless sensor networks is investigated and a mathematical framework is developed for asynchronous communications using a Gaussian approximation method to model the multiple-access interference.
