A reflective device for use in an optical measuring system and for arranging in a measuring object is presented. The reflective device comprises an optical deflection device and a retroreflector. The deflection device is configured to deflect a light beam arriving at the optical deflection device from an incident axis of the light beam. The retroreflector is configured to reflect the light beam parallel to its respective incoming direction for each of various incoming directions of a light beam onto the retroreflector. The retroreflector and the optical deflection device are arranged in the reflective device in such a way and the reflective device can be arranged in the measuring object in such a way that a measuring beam of the optical measuring system, which is pointed at the measuring object and arrives at the optical deflection device in a first direction, is deflected by the optical deflection device onto the retroreflector in a second direction different from the first direction and, following reflection at the retroreflector, is deflected by the optical deflection device in reverse parallel to the first direction. An optical measuring system, a flying object and a flying object system are further described.

A wireless communication unit for compensating for Ionospheric group delay in a satellite communication system is described. The wireless communication unit comprises: a receiver configured to receive a multi-carrier signal from a satellite; and a processor coupled to the receiver. The processor is configured to: process the multi-carrier signal to produce a plurality of digital representations of individual carriers of the multi-carrier signal; estimate, from the plurality of digital representations of individual carriers of the multi-carrier signal, a Total Electron Content, TEC, value associated with a communication path between the satellite and the wireless communication unit through Earth's Ionosphere; and apply compensation for Ionospheric group delay subjected to the multi-carrier signal based on the determined TEC value.

The invention relates to noise distribution shaping for signals, particularly for the application in receivers for CDMA signals. An embodiment of the invention provides a method for noise distribution shaping for signals comprising the acts of generating a blanking control signal by comparing a received signal comprising transitions with at least one blanking threshold (S10), determining transitions of the received signal and zones around the determined transitions, and generating a transitions control signal comprising the determined transitions and zones (S11), adapting the at least one blanking threshold or the received signal according to an offset value depending on the amplitude of the received signal and on the transitions control signal (S12, S13, S14), and modifying the noise distribution of the received signal by applying blanking of the received signal under control of the blanking control signal (S16).
