    • A method of communicating data in a system having a plurality of transmitters each adapted to transmit a radio signal, and a receiver situated at a distance from the transmitters to receive and process the signals transmitted by the transmitters, information for transmission being subdivided into N-bit symbols, the method consisting in: giving a numerical value to each symbol; and compressing the data using a CHIP encoding technique in which the values of the symbols are transposed to an encoded value having x digits in a base B, each digit subsequently being represented in the form of n chips, the base B, the number n of chips, and the number x of digits for an encoded value satisfying the following conditions: B≦2&ngr; and 2N≦B&xgr;  so that the total number of chips x.n representing the coded value is less than 2.N.
    • 一种在具有多个发射机的系统中传送数据的方法,每个发射机各自适于传送无线电信号;以及接收机,位于离发射机一定距离处,以接收和处理由发射机发射的信号,用于传输的信息被细分为N- 位符号,该方法包括:给每个符号的数值; 并且使用其中将符号的值转置到在基数B中具有x位数的编码值的CHIP编码技术来压缩数据,随后以n个码片的形式表示每个数字,基数B,码片数n 以及满足以下条件的编码值的数字数x:使得表示编码值的码片xn的总数小于2.N。

    • The coil according to the invention has normal dimensions, but contains a considerable optical fiber length.It is constituted by a main cylindrical support (12) about which is wound a first part (18) of the optical fiber (16), which is to be unwound by pulling. It is constituted by a first concentric, supplementary cylindrical support (14) placed within the main cylindrical support (12), a second part (20) of the optical fiber (16) being wound around said first supplementary support (14), the inner layer of the first part (18) of the optical fiber (16) being directly connected to an outer layer of the second part (20) of the optical fiber (16).
    • 根据本发明的线圈具有正常尺寸,但是包含相当大的光纤长度。 它由主圆柱形支撑件(12)构成,围绕该主圆柱形支撑件卷绕光纤(16)的第一部分(18),该第一部分(18)将通过拉动而被退绕。 它由一个放置在主圆柱形支撑件(12)内的第一同心辅助圆柱形支架(14)构成,光纤(16)的第二部分(20)围绕所述第一辅助支撑件(14)缠绕,内部 光纤(16)的第一部分(18)的层直接连接到光纤(16)的第二部分(20)的外层。
