Abstract: Methods, systems, and devices for a decision directed multi-modulus searching algorithm are described. A receiver may receive a signal including a set of data symbols. The receiver may iteratively determine a set of centroids for demodulating the set of data symbols (e.g., as part of a training procedure). The centroids may be used to demodulate the set of data symbols according to a modulation constellation associated with the set of data symbols. The training procedure may include, for each data symbol of a subset of data symbols, assigning a centroid of the set of centroids to each data symbol and updating the set of centroids based on assigning the centroid to each data symbol. The receiver may demodulate the set of data symbols based on the updated set of centroids.

Abstract: A wireless communications system includes a feedback processing unit for analyzing captured bandwidth data from a remote radio head, and a problem-type processor in operable communication with the feedback processing unit. The problem-type processor is configured to (i) analyze the captured bandwidth data to determine whether the captured bandwidth data presents one of a computational polynomial time problem and a non-deterministic polynomial-time hard (NP-hard) problem, and (ii) transmit problem-specific data based on the determination. The system further includes a communications processor in operable communication with the problem-type processor. The communications processor is configured to process polynomial time problem data from the transmitted problem-specific data. The system further includes a quantum computer in operable communication with the problem-type processor. The quantum computer is configured to process NP-hard problem data received from the transmitted problem-specific data.

Abstract: A local communication network (LCN) is contemplated. The LCN may be established within an existing network by leveraging network capabilities in order to facilitate local communications of the type whereby point-to-point (P-to-P) or other types of messaging and/or signaling may be communicated directly between devices without having to be relayed through a headend, a termination system or other processing entity.

Abstract: A profile optimizing method is provided for a downstream channel transmission of active subcarriers to user devices. The method includes steps of receiving channel measurement data from each user device for each subcarrier, calculating a maximum bit-loading value for each user device per subcarrier, grouping the user devices into a plurality of clusters based on a proximity of the maximum bit-loading values of a first user device to those of a second user device within the particular cluster, assigning each user device within the particular cluster to a single cluster profile. A plurality of single cluster profiles for the plurality of clusters forms a set of cluster profiles. The method further includes steps of determining a channel capacity ratio for the set of cluster profiles, and combining at least two single profiles of the set of cluster profiles into a coalesced profile pair.

Abstract: A coordinated multiple-AP system and method for alleviating AP overloading, sticky clients, and RF interference for use in a non-WLAN Controller (WLC) communication environment, such as a home network. In the present system and method AP periodically measure the communication environment and share the measured data with other APs in the same communication environment. The shared communication environment data is utilized to collaboratively determine best data transmission scenarios for supported clients. Best data transmission scenarios include but are not limited to optimized Client Link Management and Radio Resource Management.
