Method and device in telecommunication system

根据发明，提供了包括相位旋转器(50)和相位调整器(52)的笛卡儿控制装置(16)。使用根据发明的方法和装置，提供了相对非相位校准的无条件稳定系统，不管输入功率的变化、温度和部件的老化。不需要对控制系统提供某些条件以确保稳定性，即，系统是非妨碍性的而且不需要离线校准。在笛卡儿控制系统中包括相位旋转器(50)和相位调整技术使之得以实现。 According to the invention, a Cartesian control means (16) comprising a phase rotator (50) and a phase adjuster (52) is provided. With a method and a device according to the invention, a system is provided that is unconditionally stable with respect to non-phase alignment, regardless of input power changes, temperature and component ageing. No certain conditions need to be placed upon the control system to ensure stability, i.e. the system is non-obtrusive and requires no off-line calibration. The inclusion of the phase rotator (50) and phase adjustment techniques into the Cartesian control system makes this possible.
