From practical and theoretical viewpoints, performance analysis of communication systems by using information-theoretic results is important. In this paper, based on our previous work on Multiple Access Channel (MAC) and Multiple Access Relay Channel (MARC), we analyze the impact of a relay on the fundamental wireless communications concept, i.e., coverage region of MARC, as a basic model for u...

There is an increasing need for satellite-derived accurate chlorophyll-a concentration (chla) products to improve fisheries management in coastal regions. However, the methods used to derive these products have to be evaluated, so the associated uncertainties are known. The performance of three atmospheric correction methods, the near infrared (NIR), the shortwave infrared (SWIR), and the Manag...

This paper describes a pattern-based approach to building packet classifiers. One novelty of the approach is that it can be implemented efficiently in both software and hardware. A performance study shows that the software implementation is about twice as fast as existing mechanisms, and that the hardware implementation is currently able to keep up with OC-12 (622Mbps) network links and is like...

A dual rate synchronous DS/CDMA system provides service to low bit rate and high bit rate users. In a fixed duration interval, a low rate user transmits one bit while a high rate user transmits M bits. The differences in the bit transmission rates result in different processing gains for each class of user. In this paper, we propose a decision feedback decorrelator for the dual rate synchronous...

During the design of ABR tra c management at the ATM Forum, we performed several analyses to ensure that the ABR service will operate e ciently over satellite links. In the cases where the performance was unacceptable, we suggested modi cations to the tra c management speci cations. This paper describes one such issue related to the count of missing resource management cells (Crm) parameter of ...

In federated learning (FL), reducing the communication overhead is one of most critical challenges since parameter server and mobile devices share training parameters over wireless links. With such consideration, we adopt idea SignSGD in which only signs gradients are exchanged. Moreover, existing works assume Channel State Information (CSI) available at both server, thus can fixed transmission...

This article describes a new system for induction of oblique decision trees. This system, OC1, combines deterministic hill-climbing with two forms of randomization to nd a good oblique split (in the form of a hyperplane) at each node of a decision tree. Oblique decision tree methods are tuned especially for domains in which the attributes are numeric, although they can be adapted to symbolic or...

Emerging Internet applications create the need for advanced packet classifiers. This paper investigates the mechanisms that determine the performance of state-of-the-art multi-field classification methods, and proposes a novel scheme called P2C for packet classification at OC-192 and OC-768 speeds. P2C combines the strengths of embedded memory and ternary CAM technologies to achieve very high s...

nowadays, compressible flow transmission pipelines are used in many industrial processes. pipelines in chemical processes, gas turbine power plants, natural gas transmission lines, and high pressure steam transmission pipelines are some industrial examples. therefore, learning the manner of treatment of a transient compressible fluid flow in pipelines with junctions and branches is important. i...
