MMSE interference suppression for direct-sequence spread-spectrum CDMA
It is concluded that MMSE detectors can alleviate the need for stringent power control in CDMA systems, and may be a practical alternative to the matched filter receiver. Expand
Blind adaptive multiuser detection
This paper introduces an adaptive multiuser detector which converges (for any initialization) to the MMSE detector without requiring training sequences and is made robust to imprecise knowledge of the received signature waveform of the user of interest. Expand
The performance of TCP/IP for networks with high bandwidth-delay products and random loss
Modifications that may be required both at the transport and network layers to provide good end-to-end performance over high-speed WANs are indicated. Expand
Space-Time transmit precoding with imperfect feedback
An information-theoretic perspective on optimum transmitter strategies, and the gains obtained by employing them, for systems with transmit antenna arrays and imperfect channel feedback is provided. Expand
On the Feasibility of Distributed Beamforming in Wireless Networks
It is shown that a large fraction of the beamforming gains can be realised even with imperfect synchronization corresponding to phase errors with moderately large variance, and a stochastic analysis is presented that demonstrates the robustness ofbeamforming gains with imperfect synchronized synchronization. Expand
Distributed transmit beamforming: challenges and recent progress
Promising recent results in architectures, algorithms, and working prototypes indicate that challenges of distributed beamforming can be surmounted, and directions for future research needed to translate the potential of distributedbeamforming into practice are discussed. Expand
Distributed Transmit Beamforming Using Feedback Control
A simple analytical model, borrowing ideas from statistical mechanics, is used to characterize the progress of the algorithm, and to provide guidance on parameter choices, and the proposed system is shown to be scalable: the random phase perturbations can be chosen such that the convergence time is linear in the number of collaborating nodes.

On the limits of communication with low-precision analog-to-digital conversion at the receiver
This work evaluates the communication limits imposed by low-precision ADC for transmission over the real discrete-time additive white Gaussian noise (AWGN) channel, under an average power constraint on the input. Expand

Blockage and directivity in 60 GHz wireless personal area networks: from cross-layer model to multihop MAC design
A diffraction-based model to determine network link connectivity as a function of the locations of stationary and moving obstacles is developed and it is shown that multihop communication, with the introduction of a small number of relay nodes, is effective in maintaining network connectivity in scenarios where single-hop communication would suffer unacceptable outages.
