Abstract: A method of data signal processing is provided, wherein the method comprises filtering a pre-filtered quadrature data signal by using an m×n filtering matrix, wherein m?n. In particular, the filtering may be performed by using a rectangular matrix, i.e. a non-quadratic matrix. That is, the filtering may be performed by a matrix multiply in an image cancellation filtering unit. In general m relates to the 5 number of rows of the matrix while n relates to the number of columns of the matrix. In particular, the processing may form or may be a part of an image cancellation process.

Abstract: The present invention relates to a process for the production of no-carrier added 99Mo by neutron activation of 98Mo thereby reaching specific radioactivity which allow the use of such produced 99Mo as an option for the 99Mo produced by the fission of 235U. This has been achieved by taking advantage of the recoil of the 99Mo nuclei upon the capture of neutrons by the 98Mo containing compound. These recoiled nuclei are no longer chemically bound to the 98Mo containing compound allowing further specific separation. Preferred 98Mo containing compounds are molybdenum(O)hexacarbonyl [(Mo(CO)6] and molybdenum (VI) di oxodioxinate [C4H3(O) —NC5H3) J2-MoO2.

Abstract: The present invention relates to a digital I/Q modulator which efficiently supports multi-time-slot operation of wireless TDMA transmitters employing linear power amplifiers. According to the present invention, dips are introduced in the envelope of the I/Q signal in the guard interval between adjacent time-slots or bursts. The dips avoid interference on adjacent radio frequency channels when the gain of the TX chain in switched abruptly in order to change the power level of the TX signal or when the modulation scheme is changed. Also, a method is provided for generating the dips, which is particularly attractive if the modulation scheme in adjacent time-slots changes from GMSK to 8PSK or vice versa.

Abstract: Simple conventional frequency measurement circuits comprise two counters as essential elements. In such counters a problem may occur that the count value has a relative error of ±1/N, corresponding to the measurement interval. According to the present invention, pairs of intermediate count values of the counters are used to estimate the frequency ratio. According to an aspect of the present invention, this may be made on the basis of the steepness of a regression line determined on the basis of the pairs of intermediate count values of the counters. Furthermore, according to an aspect of the present invention, both counters continue counting while the intermediate sample values are sampled.
