This paper analyzes the receiver's ability to differentiate between multiple users in ultra-wideband (UWB) impulse radio (IR) during the initial synchronization phase after a cold start, i.e., when the receiver is not yet synchronized with the user of inte ...

As the demand for wireless mobile communication services is constantly growing, the need for mobile systems and devices that support much higher data rates is increasing. The available bandwidth is limited and expensive, thus we need new technologies that ...

In this paper we determine bounds of the capacity region of a two-user multiple-access channel with Rayleigh fading when neither the transmitters nor the receiver has channel state information (CSI). We assume that the fading coefficients as well as the ad ...

Performance limits for multiple-access channels are well known as long as the messages of different nodes are independent. Considerable research efforts have been devoted to the problem when the source information is dependent across nodes, revealing capac ...

Kalman filtering has been proposed in the literature for wireless channel estimation, however, it is not sufficiently robust to uncertainties in the channel auto-correlation model as well as to multiple access interference (MAI). This paper presents a rece ...

An upper bound is established on the usefulness of noisy feedback for the two-user multiple-access channel (MAC). The bound generalizes a dependence-balance argument developed by Hekstra and Willems for the common-output two-way channel and the MAC with no ...

We present a new scheme that mimics pattern formation in biological systems to create transmission patterns in multi-hop ad hoc networks. Our scheme is decentralized and relies exclusively on local interactions between the network nodes to create global tr ...
CDMA and MIMO-CDMA systems using RAKE receivers are heavily limited by self- and multiple-access-interference. Linear equalization is a means to remove this interference, however it is often not practical due to the enormous complexity, especially in the M ...

Multi-user multiple-input multiple-output (MU-MIMO) wireless systems can provide a substantial gain in network downlink throughput by allowing multiple users to communicate in the same frequency and time slots. The challenge is to design transmit beamformi ...
