    摘要： A wireless data transmission method and apparatus are provided for compensating a distortion due to a clipped amplitude when an amplitude of a signal is clipped to reduce a peak to average power ratio (PAPR) in a wireless communication system using an orthogonal frequency division multiplexing (OFDM) scheme and a transmit diversity method using an orthogonal coding. The wireless data transmission apparatus includes a coding unit which Space-Time block codes a first data stream into a plurality of second data streams, the plurality of second data streams being orthogonal to each other; an inverse Fourier transform unit which performs an inverse Fourier transform of each of the Space-Time block coded second data stream and generates a plurality of time domain signals; and a plurality of amplitude clipping units which clips an amplitude of each of the plurality of generated time domain signals.

    摘要： A technique to encode a group of vectors by quantizing the group with each of a number of different codes (44) and selecting the quantization results which are most favorable. This technique may include providing several vectors to an encoder (40) of a communication system (20) and quantizing each of the vectors with a number of different codebooks (44) to generate a corresponding number of codeword sets with the encoder (40). The codeword sets are each representative of the vectors. Each of the codeword sets is evaluated by determining a corresponding distortion value. The codeword set with the lowest distortion is selected to encode the vectors based on this evaluation. The codebook (44) or sequence of codebooks (44) used to generate the selected codeword set may differ from one vector sample to the next to provide a sample adaptive coding scheme. Transmission of the encoded data to a decoder (50) of communication system (20) may also be performed where the original vectors are reconstructed.

    摘要翻译： 一种通过用多个不同代码（44）中的每一个量化该组来编码一组矢量并选择最有利的量化结果的技术。 该技术可以包括向通信系统（20）的编码器（40）提供若干向量，并用多个不同的码本（44）对每个向量进行量化，以生成具有编码器（40）的相应数量的码字集合。 码字集合各自代表向量。 通过确定相应的失真值来评估每个码字集合。 选择具有最低失真的码字组以基于该评估对矢量进行编码。 用于生成所选择的码字集合的码本（44）或码本序列（44）可以不同于一个向量样本到下一个向量样本，以提供样本自适应编码方案。 编码数据到通信系统（20）的解码器（50）的传输也可以在重构原始矢量的地方进行。

    摘要： Provided is an IV flow controller which adjusts the amount of an IV material supplied to a patient through an IV tube and to which a flushing feature is added. The IV controller according to the present invention includes: a first body unit, a second body unit, a fixed roller, and a driving roller. The fixed roller is fixedly and rotatably arranged, and has a first gear unit and a second gear unit. The driving roller is accommodated such that a portion thereof is exposed, and the driving roller is moved along the lengthwise direction while controlling the flow of the IV when the exposed portion is turned. Also, in the flushing position, the driving roller rotates in cooperation with the first gear unit of the fixed roller across the IV tube so as to flush the latter. The second gear unit of the fixed roller may be configured so as to have a ratchet gear, and the second body unit has a pawl which meshes with the ratchet gear of the fixed roller in order to prevent reverse rotation. According to the present invention, flushing in the reverse direction is prevented by the ratchet gear, and thus medical accidents caused by reverse flushing can be prevented.
