    摘要: In one embodiment of the instant invention, a non-coherent transmission method for uplink control signals is provided. The transmission methodology uses a constant amplitude zero-autocorrelation (CAZAC) sequence for relatively short control signal lengths. The methodology includes creating a CAZAC sequence, truncating the CAZAC sequence into a plurality of segments; and transmitting each of the segments within a predetermined window of time.

    摘要: Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition.The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
