Abstract: A technique for construction of finite-length low-density parity check (LDPC) codes is herein disclosed which advantageously provides a flexible tradeoff of low decoding thresholds and low error-floors.

Abstract: A method and system are disclosed that improve the efficiency of a time division duplex communication system. The uplink transmission slots of a plurality of mobile stations are arranged in an order so as to take advantage of the short propagation delay to the closest mobile stations, thereby advantageously resulting in a time division duplex guard time which is potentially independent of cell size.

Abstract: This invention relates to a method of manufacturing a golf club shaft and in particular to one including steps of prefabricating a conical tubular member having a larger end and a smaller end, connecting a handle grip with the larger end of the conical tubular member, and inserting a blowing tube into the handle grip and the conical tubular member for blowing pressurized gas into the handle grip and conical tubular member to harden the connection between the conical tubular member and the handle grip, whereby the golf club shaft is of sturdy strength and the handle grip will not be detached from the golf club shaft inadvertently.
