摘要： A decoding scheme for determining the information within a coded transmission includes a spherical decoder candidate search that reduces the number of candidate symbol combinations from a much larger number of possibly transmitted combinations. In one example, the spherical decoder uses an upper triangular matrix representation of the channel matrix as part of a recursive, cumulative cost function that provides the results of the candidate search. The candidate search includes considering symbols in a hierarchy or tree structure that represents the possibly transmitted combinations. The cost function incrementally accumulates a cost of a possible combination as the search progresses through the hierarchy. As soon as a symbol is determined to not be a valid candidate, all possible combinations including that symbol are discarded without considering them, directly.

摘要： Methods of managing storage of HARQ packets are disclosed. One method includes a wireless device receiving variable length HARQ packets. The wireless device performing an error check on each received variable length HARQ packet, and storing within HARQ memory the HARQ packets that fail the error check. Each failed HARQ packet is stored in the HARQ memory by dividing the HARQ packet into HARQ sub-packets, and storing each HARQ sub-packet. The storage locations and storage order of each of the HARQ sub-packets are recorded for future retrieval.

摘要： Embodiments describe a method of measuring noise and interference within transceivers of an OFDM wireless transmission system, or similar communication system, including a number of receivers communicating with one or more base stations in cell or sector arrangements. The transmitter schedules a transmission burst for a non-existent user (receiver) using wireless transmission traffic. In an OFDM system, this corresponds to a certain set of subcarriers in the time/frequency arrangement. Thus, in the receive frame structure, the data and pilot subcarriers are guaranteed to be only noise and interference from adjacent sectors. The receiver can accurately measure the noise and interference without needing to cancel out the transmitted signal. Therefore, the system is assured that there is no desired signal as part of this measurement. The noise and interference measurement process can be appropriately scheduled so that it does not impact the overall throughput of the system. This mechanism creates a deterministic place (in time and/or frequency) within the transmission, where no desired signal is required.

摘要： A control mechanism pins an optical fiber assembly on and off gimbal and between gimbals to route the assembly from an off-gimbal optical source across the gimbal axis/axes to an on-gimbal optical element so that the fiber assembly moves with the rotation of the gimbals. To accommodate a relatively large range of motion, the control mechanism is suitably configured to route the fiber assembly in a “U-shaped” loop with one end pinned off-gimbal in a stationary guide track and the other end pinned on-gimbal point in a rotating guide track so that the loose fiber assembly is constrained in the concentric tracks on and off gimbal. As the gimbal rotates, the loop seats onto one guiding track and peels off of the other guiding track while always maintaining its U shape. To accommodate a relatively small range of motion in other gimbal configurations, the control mechanism is suitably configured to pin one end of the fiber assembly off-gimbal and pass the fiber assembly directly over the gimbal where it is pinned on the other side of the gimbal. In a multi-gimbal pointer, the fiber assembly preferably exhibits different mechanical stresses as it crosses the different gimbals.

摘要： A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing, before the conduit is deployed downhole. The electric cable is inserted into the conduit at the surface and is permitted to buckle in a manner so that the electric cable buckles and uniformly contacts an interior surface of the conduit at a plurality of locations along the entire length of coiled tubing to prevent longitudinal movement of the electric cable within the conduit. An electric submergible pumping system is then connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. The electric submergible pumping system and the conduit are inserted into the wellbore.

摘要： A cube puzzle solver includes: a position sensing element; at least one user interface (UI) output; and a controller that receives position information from the position sensing element, determines a suggested move, and directs the at least one UI output to provide an indication associated with the suggested move. An automated method of determining a position of a cube puzzle solver includes: monitoring a set of sense pins; identifying rotation based on a change in state of at least one sense pin; identifying a face associated with the identified rotation; and updating a state of the cube puzzle solver based on the identified face and the identified rotation. A cube puzzle system includes: a cube puzzle device including: a wireless communication interface; and a user device communicatively coupled to the cube puzzle solver over the wireless communication interface.
