Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to tone mapping techniques and packet designs that support duplicate (or “DUP mode”) transmissions to multiple users. In some implementations, an access point (AP) may transmit a PPDU that includes first user data and second user data, where at least the first user data is transmitted in a DUP mode. As such, the first user data may be mapped to a number (N) of tones spanning a first RU in accordance with a dual carrier modulation (DCM) scheme, and a duplicate copy of the first user data may be mapped to N tones spanning a second RU in accordance with the DCM scheme. In some implementations, the second user data also may be transmitted in a DUP mode.

Abstract: A data modulation method includes receiving a bit string at a processor, and identifying a set of binary strings based on the bit string. Each binary string from the set of binary strings is mapped to an element from a set of elements of a lattice-based signal constellation, without using a lookup table. Real-valued points from the set of elements are identified based on the mapping. The method also includes causing transmission of a signal having a modulation based on the real-valued points.

Abstract: Probabilistic shaping quadrature amplitude modulation (QAM) based on Maxwell-Boltzmann distribution is particularly important in coherent optical communication, which can approach the Shannon limit more desirably in the case of a finite signal-to-noise ratio. However, standard coherent optical digital signal processing algorithms are not optimal for demodulation of PS higher-order QAM signals. The invention provides a probabilistic shaping QAM dynamic equalization method that intercepts multiple inner rings after clock recovery and updates the convergence radius and area of a conventional blind dynamic channel equalization algorithm using a peak density K-means clustering algorithm. The clustering algorithm gives centroid labels and a quantity of classifications required for K-means, which does not require a large number of iterations of K-means, thereby reducing the complexity and improving the accuracy.

Abstract: A visibility platform can be used to monitor traffic traversing private cloud infrastructures and/or public cloud infrastructures. In some instances, the traffic is provided to a set of network services that are accessible to the visibility platform. These network services can be provisioned in a serial or parallel fashion. Network service chaining can be used to ensure that traffic streams skip unnecessary network services and receive only those network services that are needed. For example, an email service chain can include virus, spam, and phishing detection, while a video streaming service chain can include traffic shaping policies to satisfy quality of service (QoS) guarantees. When the visibility platform is represented as a graph that makes use of action sets, network service chains can be readily created or destroyed on demand.

Abstract: Disclosed embodiments provide a virtual topology in response to an allocation request. The virtual topology is a synchronized subgraph of the physical topology. The synchronized subgraph virtual topology mirrors the physical topology in terms of tree structure. However, merely sharing the physical topology with users/customers is not feasible, as it may reveal additional infrastructure details such as MAC addresses, IP addresses, and the like, that can compromise security and/or jeopardize multi-tenant operations. Disclosed embodiments create virtual topology structures with obfuscated node data, so that important data such as physical IP addresses and/or MAC addresses are hidden from the end-users. Thus, disclosed embodiments provide the benefits of performance enhancement that comes from sharing the topology without the downside of compromising security by revealing physical topology details.

Advantageously, the disclosed system allows users to create custom anomaly detection triggers for different types of time series data, without use of a monolithic detection model which can be difficult to tune.
