摘要： It is described a technique to compensate the in-band ripple of filters at the IFFT prior to filtering in the transmitter or, for the receiver, in the FFT after filtering. A transmitter, includes a multiplier for multiplying at least one transmitter coefficient to an input signal of an inverse Fourier transformer which is followed subsequent signal processing chain thereby reducing a ripple on the output of said signal processing chain. A receiver for receiving a transmission signal includes a signal processing chain for processing the transmission signal a multiplier for multiplying at least one receiver coefficient to an output signal of a Fourier transformer to which the output of the signal processing chain is fed to thereby reduce a ripple on said output signal of said Fourier transformer.

摘要： In sending a transmission signal, in particular a mobile radio signal, to a receiver, the transmission signal is processed according to a modulation coding scheme MCS and subjected to amplitude limited to obtain a specified ratio of maximum to average transmission power PAR. A limit value EVM for an error in the transmission signal is matched to transmission conditions for the transmission signal, according to demand, in such a way that a maximum signal to interface ration is achieved at a receiver.

摘要： A method for clipping a baseband input signal filters the complex baseband input signal with a function H1 for forming a filtered first signal. To form a clipped signal in the baseband the filtered first signal is multiplied by a scaling factor. By a signal analysis of the filtered first signal signal overshoots are predicted from which the scaling factor is determined for the baseband clipping. The filter function H1 is calculated as the quotient from a frequency response HS of a transmission filter used one the one hand and from an error frequency response HF on the other hand, with the error frequency response HF being determined in such a way that the error spectrally shaped with HF, which arises for the limitation of the baseband signal, a frequency-dependent tolerance is not exceeded. Subsequently the clipped signal is filtered with the error frequency response HF for forming a filtered second signal.

摘要： An apparatus produces a reduction signal for a signal having a plurality of subcarriers. The apparatus has a limiter which is designed to produce a limited signal from the signal having a plurality of subcarriers; -a coefficient ascertainment unit which is designed to determine coefficients for unused subcarriers of the signal having a plurality of subcarriers from the limited signal; and -a signal generator which is designed to generate the reduction signal from the coefficients. The reduction signal is able to be combined with the signal in order to form a reduced signal. The coefficient ascertainment unit is designed to project the limited signals onto a K-th base formula.

摘要： A pair of mating gears are mounted for rotation about respective axes in a gear-type fluid displacing pump or motor. Each gear has a pair of shaft portions at opposite axial ends of the respective gear, and bearing members surround respective ones of the shaft portions for journalling the gears. Each bearing member of one of the gears is juxtaposed with a respective bearing member of the other of said gears and, during rotation of the gears, the juxtaposed bearing members are subjected to forces which urge the bearing members to move relative to each other, particularly in direction towards each other. An arrangement is provided to counteract such forces and to oppose such relative movement of the juxtaposed bearing members.
