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 ...
Distributed Detection From Multiple Sensors with Correlated Observations.
(1989)
We address two problems of memoryless distributed dependent observations across time and sensors. In the first problem, the observation sequence of each sensor consists of common weak signal in additive dependent noise ...
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 ...
Multiple-Access Capability of Frequency-Hopped Spread-Spectrum Revisited: An Exact Analysis of the Effect of Unequal Power Levels.
(1988)
In this paper we present a new method for the evaluation of the probability of error of uncoded frequency-hopped spread-spectrum multiple-access (FH/SSMA) communications. For systems with binary FSK modulation the method ...
Throughput and Packet Error Probability for Cellular Direct- Sequence and Hybrid Spread-Spectrum Radio Networks.
(1988)
In this paper multiple-access interference is characterized for cellular mobile networks, in which users are assumed to be Poisson-distributed on the plane and to employ direct-sequence or hybrid (frequency-hopped/direct-sequence) ...
Analysis of Coherent Random-Carrier CDMA and Hybrid WDMA/CDMA Multiplexing for High-Capacity Optical Networks.
(1989)
In this paper we provide an accurate analysis of the performance of a random-carrier (RC) code-division multiple-access (CDMA) scheme recently introduced for use in high-capacity optical networks. According to this scheme ...
Noncoherent Hybrid DS-SFH Spread-Spectrum Multiple-Access Communications.
(1986)
The performance of noncoherent reception in synchronous hybrid direct-sequence/slow-frequency-hopped spread-spectrum multiple- access communication systems operating through additive white Gaussian noise channels is ...
Robust MINIMAX Source Coding with a Fidelity Criterion.
(1986)
The problem of minimax robust source coding under a fidelity criterion for sources whose statistics belong to uncertainty classes determined by 2-alternating Choquet capacities is examined. We consider (i) single-letter ...
