Coded FH/SS Communications in the Presence of Combined Partial- Band Noise Jamming, Rician Nonselective Fading and Multi-User Interference.
(1987)
In this paper we address the problem of combatting combined interference in spreadspectrum communication links. We consider frequency-hopped spread-spectrum systems with M-ary FSK modulation and noncoherent demodulation ...
Robust Matched Filters for Optical Receivers.
(1987)
The problem of designing optical receivers that are robust against uncertainty in the statistics of the observation process in photodetection is investigated. In particular, a modification in the design of the post-detection ...
Expected Forward Progress and Throughput of Multi-Hop Frequency- Hopped Spread-Spectrum Networks.
(1987)
Secondary multiple-access interference processes are characterized for multi-hop packet radio networks, in which users are assumed to be Poisson-distributed in the plane and to use frequency-hopped spread-spectrum signaling ...
Probability of Capture and Rejection of Primary Multiple-Access Interference in Spread-Spectrum Networks.
(1987)
The probability of capture is evaluated for the situation in which several transmitters use the same spread-spectrum code to contend for the attention of a single receiver. The first stage in the capture mechanism is that ...
On Robust Continuous-Time Discrimination.
(1987)
Continuous-time discrimination problems characterized by observations which are the output of stochastic dynamical systems driven by colored Gaussian noise are considered. The parameters of the dynamical systems belong to ...
Throughput of Hybrid (DS-SFH) Spread-Spectrum Random-Access Communications.
(1987)
The multiple-access capability of hybrid direct-sequence slow frequency hopped (DS-SFH) spread-spectrum systems with forward- error control coding is investigated. Frequency-slot synchronous and asynchronous schemes, packet ...
Collision Resolution Algorithms for Networks with Spread- Spectrum Capture Capability.
(1987)
In networks which employ spread-spectrum signaling, capture and correct reception of one out of several packets transmitted to a common receiver by contending users is possible. For the case in which all the contending ...
Minimax Robust Matched Filters for Noise Uncertainty Within 2- Alternating Capacity Classes.
(1987)
In this paper, we address the problem of designing matched filters which are robust against uncertainty in the statistics of the noise process. The design is based on a game-theoretic approach in which a filter is sought ...
Robust Distributed Discrete-Time Block and Sequential Detection in Uncertain Environments.
(1987)
Two detectors making independent observations must decide which one of two hypotheses is true. Both fixed-sample-size (block) detection and sequential detection are considered. The decisions are coupled through a common ...
Robust Distributed Block and Sequential Continuous-Time Detection.
(1987)
Two detectors making independent observations which are the outputs of stochastic dynamical systems driven by colored Gaussian noise must decide which one of two hypotheses is true. Detection with a fixed observation ...
