摘要:
A greater likelihood decoder, a method of deriving a reduced substreams maximum likelihood (RSML) decoded symbol vector and a multiple-input, multiple-output (MIMO) receiver incorporating the decoder or the method. In one embodiment, the decoder includes: (1) a suboptimal decoder that analyzes a received symbol vector to generate substream indicators and a decoded symbol vector estimate, (2) weakest substreams decision logic, coupled to the suboptimal decoder, that receives the substream indicators and selects weakest ones thereof and (3) subspace search logic, coupled to the suboptimal decoder and the weakest substreams decision logic, that further selects a reduced substreams maximum likelihood (RSML) decoded symbol vector from a subspace of decoded symbol vector candidates derived from the decoded symbol vector estimate and the weakest ones.
摘要:
Aqueous disinfecting and cleaning compositions and concentrates which are efficacious against gram positive and gram negative bacteria, have relatively low volatile organic content (“VOC”) and are surprisingly mild to the user of the compositions. The compositions include a quaternary ammonium compound as its primary germicidal active agent, have a low content of active constituents, and do not include organic solvents such as alcohols, glycols, or glycol ethers in significant amounts.

Provided are a data transmitting and receiving method for a multiple-input multiple-output (MIMO) communication system, and a transmitter and a receiver using the method. Accordingly, since precoding matrices of a codebook is constituted using a rotation matrix, expansion of the codebook is easy, and since each of the precoding matrices is determined according to the number of transmit antennas, the codebook is systematically created according to a system. In addition the codebook can be applied to even a correlated channel, and the minimum distance between precoding matrices can advantageously be maximized.
摘要:
Techniques and structures have been developed for providing lead-free column grid array interconnect structures. An exemplary interconnect has a body, a first joint, and a second joint, all having compositions off the eutectic composition in a ternary alloy system, the first joint having a ternary composition distinct from the body composition, and the second joint having a ternary composition distinct from the body composition and the first joint composition. The interconnect may be formed by solidifying a solder, having a Sn-poor ternary composition in the Sn—Ag—Cu alloy system, in contact with a column, having a Ag-rich Cu-deficient composition in the same system, and a bonding pad or bare substrate. A second solder, having a Sn-rich ternary composition, may be solidified in contact with the column and a second bonding pad or bare substrate. In some embodiments joints may be severed and reformed by remelting and resolidifying the lower-liquidus solder.

摘要:
A mixing device comprising cooperating rotor and stator elements wherein a stator blade is arranged at the inlet to the stator element for cooperation with an axially outer end of at least one rotor blade. In use, fibrous material which is drawn into the stator element by rotation of the rotor element is shredded by the action of the cooperating rotor and stator blades. The material is then expelled radially outwardly from the stator element and is subjected to high shearing forces, which effect further mixing and disintegration, as it passes between a radially center edge of a rotor blade and the stator elements.
