摘要： A radio receiver system (30) comprises a radio receiver (41), a receiver sample clock (60), which is used for sampling a modulated base-band signal; and a timing correction unit (100). The timing correction unit (100) performs, in the frequency domain, a timing drift compensation between a transmitter sample clock (66) and the receiver sample clock (60). In one example context of implementation, the plural modulated radio frequency carriers have been modulated using Orthogonal Frequency Division Multiplexing (OFDM).

摘要： The invention relates to simulation of effects in a combat environment, wherein personnel, vehicles and buildings are exposed to simulated fire from military weapons. Direct fire and indirect fire are simulated by means of at least one of light rays and radio waves. Effects of attacking fire are registered by means of a target object device, which includes sensors adapted to detect the light rays respective the radio waves and are co-located with the target object (140). According to the invention the target object is associated to at least one protecting object located between the simulated fire and the target object if such object exists in the current combat situation. This enables a consideration to various protecting object— influence on the simulated fire and the effects on corresponding actual fire. The invention thereby simulates the effects of direct fire and indirect fire in a realistic manner, which in turn provides good chances of an adequate behavior of the training personnel in a corresponding live situation.

摘要： A semiconductor arrangement is provided for generating a predetermined time delay. Two clocks are connected to two parallel, redundant semi-conductor circuits emitting clock signals from multiplexers. The redundant circuits receive delayed clock signals from one of the clocks, and from the other clock, clock signals that are delayed in adjustable delay circuits to be phased in with the clock signals from the first clock. A number of delay elements and a first reference number of delay elements, providing a predetermined delay time, are connected in a reference delay circuit. A quotient of the two numbers is stored. One of the semi-conductor circuits is replaced by an alternative semi-conductor circuit, the reference delay circuit of which is set on the predetermined delay time, corresponding to a second reference number of delay elements. An adjustable delay circuit is set on the same delay time as the replaced semi-conductor circuit by means of the second reference number and the quotient.
