Abstract:
(EN) Provided in embodiments of the present invention are a transmitter, a receiver and a signal processing method. The transmitter comprises a constellation mapper (310), a signal conversion module (320), a digital signal processor (330) and a digital analog converter (340); the constellation mapper (310) is used for determining a mapping relationship between a bit stream and a constellation point in polar coordinates, and generating a constellation symbol data stream according to said mapping relationship; the signal conversion module (320) is used for converting the constellation symbol data stream into an amplitude signal and a phase signal, wherein the amplitude signal is a 2-level analog signal and the phase signal is an 8-level digital signal; the digital signal processor (330) is used for subjecting the phase signal to digital signal processing, thus generating a multi-level digital signal; and the digital analog converter (340) is used for converting the multi-level digital signal into a multi-level analog signal. By virtue of the embodiments of the present invention, the complexity, power consumption and cost of a communication system can be reduced.
(FR) La présente invention concerne un émetteur, un récepteur et un procédé de traitement de signal. L'émetteur comprend un dispositif de cartographie de constellation (310), un module de conversion de signal (320), un processeur de signal digital (330) et un convertisseur d'analogie digital (340) ; le dispositif de cartographie de constellation (310) est utilisé pour la détermination d'une relation de mappage entre un élément binaire de diffusion et un point de constellation dans des coordonnées polaire, et génère une diffusion de données de symbole de constellation en fonction de ladite relation de mappage ; le module de conversion de signal (320) est utilisé pour convertir la diffusion de données de symbole de constellation dans un signal d'amplitude et un signal de phase, le signal d'amplitude étant un signal d'analogie de niveau-2 et le signal de phase étant un signal digital de niveau-8 ; le processeur de signal digital (330) est utilisé pour soumettre le signal de phase au traitement de signal digital, générant alors un signal digital multi-niveau ; et le convertisseur d'analogie digital (340) est utilisé pour convertir le signal digital multi-niveau en signal d'analogie multi-niveau. En vertu d'un des modes de réalisation de la présente invention, la complexité, la puissance de consommation et le coût d'un système de communication peut être réduit.
(ZH) 本发明实施例提供了一种发射机、接收机和信号处理的方法。该发射机包括星座映射器(310)、信号转换模块(320)、数字信号处理器(330)和数字模拟转换器(340);该星座映射器(310),用于确定比特流与极坐标下的星座点的映射关系,并根据该映射关系生成星座符号数据流;该信号转换模块(320),用于将该星座符号数据流转换为幅度信号和相位信号,其中,该幅度信号为2电平模拟信号,该相位信号为8电平数字信号;该数字信号处理器(330),用于将该相位信号进行数字信号处理,生成多电平数字信号;该数字模拟转换器(340),用于将该多电平数字信号转换为多电平模拟信号。本发明实施例能够降低通信系统的复杂度、功耗和成本。
