Abstract:
(EN) Provided in the present application are a method and an apparatus for transmitting a signal. The method comprises: combining a plurality of low-order modulated signals into K high-order modulated signals; transmitting the K high-order modulated signals through L antennas, wherein the high-order modulated signals transmitted on a i-th channel corresponding to a m-th antenna in the L antennas and the high-order modulated signals transmitted on a j-th channel corresponding to a n-th antenna are formed by combining the same low-order modulated signals, K being a positive integer greater than or equal to 2, L being a positive integer greater than or equal to 2, m and n being positive integers less than or equal to L, m ≠ n, and i and j being positive integers. Thereby, it is possible to realize a spatial diversity of signal transmission, and the reliability of signal transmission and the performance of the communication system can be improved.
(FR) La présente invention concerne un procédé et un appareil de transmission de signaux. Le procédé consiste à : combiner une pluralité de signaux modulés d’ordre faible en K signaux modulés d'ordre élevé ; et transmettre les K signaux modulés d'ordre élevé via L antennes. Les signaux modulés d'ordre élevé transmis sur un canal i correspondant à une antenne m parmi les L antennes et les signaux modulés d'ordre élevé transmis sur un canal j correspondant à une antenne n sont formés par la combinaison des mêmes signaux modulés d'ordre inférieur. K est un nombre entier positif supérieur ou égal à 2, L est un nombre entier positif supérieur ou égal à 2, m et n sont des entiers positifs inférieurs ou égaux à L, m ≠ n, et i et j sont des entiers positifs. L’invention permet de réaliser une diversité spatiale de transmission de signal, et d’améliorer la fiabilité de transmission de signal et la performance du système de communication.
(ZH) 本申请提供一种传输信号的方法和装置,该方法包括:将多个低阶调制信号组合成K个高阶调制信号;通过L个天线传输该K个高阶调制信号,其中,该L个天线中第m天线对应的第i信道上传输的高阶调制信号与第n天线对应的第j信道上传输的高阶调制信号由相同的低阶调制信号组合而成,K为大于或等于2的正整数,L为大于或等于2的正整数,m,n为小于或等于L的正整数,且m≠n,i,j为正整数。由此,能够实现信号传输的空间分集,提高信号传输的可靠性和通信系统的性能。
