    摘要: A system and method for rate matching to enhance system throughput based on packet size is provided. A method for transmitting information includes encoding a block of N bits, where N is an integer, demultiplexing the encoded block of N bits into at least one subblock of systematic bits and at least one subblock of parity bits, and permuting the at least one subblock of systematic bits and the at least one subblock of parity bits to generate at least one permuted subblock. The method also includes forming at least one output block from the at least one permuted subblock, computing a starting position of a redundancy version for a hybrid automatic repeat request (HARQ) transmission based on a relationship between N and a threshold, and transmitting the redundancy version. The redundancy version begins at the computed starting position and ends when a specified number of bits has been transmitted.

    摘要: An embodiment of Vertical Axis Wind Turbine (VAWT) concept with eight rotating impellers with eight rotating wind vanes, wherein each wind vane is attached to each impeller through the vane angle adjusting devices is described. Further described is the vane angle adjusting device with coupling blocking fork and the impeller with the high load capacity and increased output. In addition, the gear reducer module and the cone clutch are described that control the power transmission from the wind vane and the impeller in case of strong gusts or wind. This feature allows for a number of improvements over the current state of the art including high energy efficiency, damage protection and the ability to remain operational during high wind conditions.
