摘要： A method for controlling a brushless DC motor (BLDC motor) having a rotor, a stator and an angle sensor and a logic circuit for generating the phase voltages of the windings depending on the phase angle of the rotor. The logic circuit access a lookup table, in which to implement commutation with block-shaped, trapezoidal, sinusoidal, sinoid-based signal waveforms. The drive values are stored for the electrical phase angle of the rotor for generating phase voltages (VU, VV, VW) for the windings. A control unit generates configuration data for the logic circuit determine the commutation form, and depending on the form, the drive values are supplied to a PWM generator for generating control signals (VU, VV, VW) depending on the electrical phase angle of the rotor angle, which PWM control signals can be used to control the phase currents in the windings.

摘要： A trailer device for driving stabilization of vehicle combinations is provided. In order to design a device for driving stabilization of passenger vehicle trailers in a cost-effective and simple manner, a brake system for braking the trailer by an overrun brake and for stability regulation is designed so as to have separating valves, switching valves, inlet and outlet valves and a pressure build-up pump. A stabilizing coupling is also connected by means of a second pressure medium pump to actuators which can vary the clamping force of the stabilizing coupling between the trailer and tractor vehicle if the second pressure medium pump conveys pressure medium from the storage tank into or out of the actuators.

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 way 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 way 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： An equalizer of a radio receiver for generating reliability information (q) that specifies probabilities of a received data symbol (z) being based on a particular transmitted value. The reliability information (q) is determined for each received data symbol (z) by evaluating trellis state transitions through use of a particular metric, both trellis-based symbols and decision-feedback symbols being evaluated. The decision-feedback symbols used are state-independent symbols that have previously been decided by means of a hard decision.

摘要： A pulse train with known values and a known length contained in a signal is identified. The mathematical sign of the phase difference between successive samples of the signal is used to assess whether the transmitted pulse is a 1 or a 0, and with the sum of the pulses being determined in a window which is proportional to the length of the pulse train. The pulse train is considered as being identified at the time when the sum of the pulses in the search window exceeds a given threshold value.
