Abstract: A method for establishing a small cell telecommunications network is provided. The method includes determining a plurality of sets of candidate locations, in which each set includes candidate locations for establishing small cell base transceiver stations to provide wireless network service. Each location in the set is determined by applying a gradient descent process to find a local optimal location. The evaluation criteria in the process can include, e.g., an estimated number of people expected to receive coverage, and/or the cost of operating the base transceiver stations. The plurality of sets are evaluated to determine a set of global optimal locations. The evaluation criteria can include, e.g., the expected revenue generated per unit time minus the cost of operating the base transceiver stations per unit time.

Abstract: A method for dynamically managing spectrum access and supporting multiple tiers of users is provided. A spectrum access server receives a request from a device to access a segment of spectrum, and determines which tier of the multiple tiers is associated with the request. If the request is from a second tier user and the request does not interfere with first tier users, the request is granted. If the request is from a third tier user and the request does not interfere with first tier users and authorized second tier users, the request is granted.

Abstract: Effects of variation in computational latency can be controlled by using a processor to perform computations associated with a signal processing process, each computation related to processing an input sample to generate an output, and allocating a processing cost per computation that is less than a maximum processing cost of the processor for performing any one of the computations and greater than an average processing cost of the processor for performing the computations. The allocated processing cost for a computation is an allocated time period between receipt of the input sample and generation of the output for the computation. A task requiring a processing time greater than the allocated processing cost is handled as a source of jitter in the signal processing process.

Abstract: A communication network topology is determined by evaluating costs of states each representing a possible assignment of hubs and remote nodes to nodes of the communication network. The hubs connect to a central network, the remote nodes connect wirelessly to the hubs and obtain connectivity to the central network through the hubs. The cost of each state is determined based on costs for configuring each node as a hub or a remote node, uplink frequencies for sending data from the remote nodes to corresponding hubs, and downlink frequencies for sending data from the hubs to corresponding remote nodes.

Abstract: Methods and related systems for controlling jitter effects are disclosed.

Abstract: Transmitting messages to mobile telephones includes determining a time a standard requires or permits a standard compliant transmission to be received by a user, and scheduling a transmission by a base station to the user in the future based on a distance between the user and a base station such that the transmission will be received by the user at the determined time. The distance between the user and the base station is a distance such that a propagation delay between the user and the base station is larger than a propagation delay accommodated by the standard.

Abstract: In one aspect the invention is a method for decoding. The method includes receiving encoded data and decoding the encoded data using a noise-adaptive decoder. The data may include first-order Reed-Mueller (FORM) based codes. The data may be based on Complementary Code Keying. Using a noise-adaptive decoder may include determining values of a hard decision based on a first decoding process and discarding the values of the hard decision if a noise sensitivity parameter is above a threshold value. The method may further include using a second decoder process if the noise sensitivity parameter is above the threshold value.

Abstract: In one aspect the invention is a method for sequence estimating. The method includes generating a dynamic programming table, which represents a trellis. The trellis includes a set of time steps, which have a set of states. The trellis also includes a number of branches that connect the states. The method also includes expanding a search along the branches having a least accumulated error, inserting a pointer into a priority queue, where the pointer indicates an end of a partially completed path within the trellis, searching other branches when the accumulated error is no longer the least accumulated error, and continuing the search until the time step equals a current time.

Abstract: A software-defined wireless communication device is disclosed that includes a hardware platform, which can be digital or analog, as well as platform software that manages the hardware profile and waveform software that manages the signal processing functions. The software-managed hardware profiles are decoupled from the signal processing functionality of the software. In this way, waveform software can be certified, for example for compliance with FCC emissions requirement, independently from the platform software and from the hardware on which the waveform software runs.
