Title: Procedure and device for estimating a propagation channel on the basis of statistics
Inventor: CHEVALIER PASCAL
IPC: H04B1/707
Filed: 2002-02-26
Abstract: The procedure for estimating the pulse response of a propagation channel includes estimation of the additive noise statistics resulting from interferences, and of the thermal noise, by analysis of the statistics of the received signal. The procedure for estimating the pulse response, h, of a propagation channel in a system comprising one or more sensors comprises at least one estimation stage. This stage comprises estimation of the additive noise statistics resulting from interferences, and of the thermal noise, by analysis of the statistics of the received signal. The procedure further includes a stage of estimating the covariance matrix of noise with respect to the empirical covariance matrix of observations, Rx, and the number of pilot signals in a learning sequence transmitted with the signal.

Title: High-voltage transformer
Inventor: BIEBACH JENS
IPC: H02M3/28
Filed: 2000-12-18
Abstract: The invention relates to a high-voltage transformer which converts the direct current voltage from a direct current voltage source (2) into a direct current voltage output signal (Vout), using a current inverter (4) and a transformer (8) and an output rectifier (12) which is connected downstream, in addition to filters (14). The transformer (8) has a transformer core comprising several interruption points in the magnetic path, at which insulator sections are located. The individual core sections are controlled by potential. The separate transformer core sections together with their corresponding windings form a primary system and a secondary system, which is separated from said primary system both spatially and in terms of potential and has a relatively high leakage inductance. Said leakage inductance is used in conjunction with other components for the resonant mode of the high-voltage transformer during the switching operations (quasi-resonant mode) and for adjusting an approximately sinusoidal transformer current using the current inverter clock cycle. At the same time, the spatial separation simplifies the insulation of the transformer parts.
