摘要:
A process for the production of 4-(heteroaryl-methyl)-halogen-1(2H)-phthalazinones, especially 4-(4-pyridylmethyl)-1(2H)-phthalazinone, is described, which is characterized by the reaction of phthalidyl-3-triphenylphosphonium salt with 4-pyridine aldehyde in the presence of a basic adjuvant, subsequent reaction with hydrazine hydrate and subsequent acid treatment, whereby this process avoids the technical safety and environmental problems of the known processes.

This invention relates to 2-heteroaryl-pyrimidine derivatives of general formula I or If as inhibitors of the cyclin-dependent kinases, their production as well as their use as medications for treating various diseases.
摘要:
A receiver device includes a first mixer for production of a first analogue intermediate signal by down-mixing of a radio-frequency signal. The device also includes an A/D converter for production of a first digital intermediate signal, a second mixer for production of a second digital intermediate signal from the first digital intermediate signal, and a third mixer for production of a digital baseband signal from the second digital intermediate signal. The second mixer has a higher sampling frequency than the third mixer.
摘要:
In order to compensate for a frequency offset or a change in the phase of the transmission channel over time during mobile radio transmission of data symbols, the data symbols are transmitted by means of carrier-frequency, modulated data bursts. Sample values of the received signal, which are known in advance and correspond to first and second symbols, are evaluated in order to estimate the frequency offset or the change in the phase of the transmission channel over time. These first and second symbols are transmitted with a defined phase angle by means of the data burst, and are arranged separated from one another in the data burst. Edge symbols in a data burst are advantageously used as first and second symbols, or as a symbol pair, for estimation.
摘要:
A method for equalization of a signal is provided, wherein the equalization is of a signal that is transmitted via a data channel based on the DF method. The method takes account of at least one interference channel, and includes processing of at least two trellis diagrams in each time unit, with the states of at least one of the trellis diagrams describing the data channel. A DF contribution that is used for processing of this trellis diagram includes information about at least one interference channel.
