摘要： In processors, notably digital signal processors, it is often necessary to form the sum of products of a concatenation of data word pairs, for example for correlation or convolution operations, in which the one data word of each pair can assume only one of the two values +1 or -1. In accordance with the invention, in that case instead of forming a product in a multiplier, the one data word of each pair is applied to an add/subtract device in order to control the function thereof in respect of addition or subtraction; one input of the add/subtract unit then receives the other data words of the data word pairs, and the other input is connected to the output of the accumulator register. Thus, a complex multiplier device is saved or, should such a device be present anyway, it will not be used so that the power loss of the processor is reduced.
摘要翻译：在处理器中，特别是数字信号处理器，通常需要形成数据字对的级联的和，例如用于相关或卷积运算，其中每对的一个数据字只能承担两个中的一个值+1或-1。根据本发明，在这种情况下，代替在乘法器中形成乘积，每对中的一个数据字被应用于加法/减法器件，以便控制加法或减法的功能; 然后，加/减单元的一个输入接收数据字对的其他数据字，另一个输入连接到累加器寄存器的输出。因此，保存复数乘法器装置，或者如果这样的装置出现，则不会使用它，以致减少了处理器的功率损耗。

摘要： A receiver for time-varying distorted data signals, includes an equalizer and a channel estimator which generates a channel information signal with the aid of a training signal sent together with the data signal and with the aid of an image of the training signal stored in the receiver, and applies this signal to the equalizer. The receiver further includes an arrangement for channel tracking which generates correction values for the channel information signal with the aid of data detected by the equalizer. At very high relative velocities between the sender and the receiver (e.g. 200 km/h when using the mobile radio set in a motor vehicle, for example) a degradation of the bit error rate is avoided in that, at least part of or the complete received training signal is applied to the arrangement for channel tracking prior to the data signals to be equalized and detected after the channel information determined on the basis of the training signal has been transmitted.

摘要： A preprocessing unit is inserted between a baseband converter and an equalizer/detector for performing a signal processing which corresponds to a phase rotation of the CPM-signal in the baseband represented by in phase and quadrature components. The phase rotation progresses in discrete steps of 90.degree. per bit interval of the binary data signal contained in the CPM-signal. The introduction of the preprocessing unit renders it possible to use a comparatively simple conventional equalizer/detector for binary pulse amplitude modulated signals (PAM-signals) for equalizing and detecting binary CPM-signals received in distorted form. When the equalizer/detector is adaptive, a further preprocessing unit is inserted between a channel estimator and adjusting inputs of the equalizer/detector.

摘要： In a base band conversion receiver, frequency deviation in the base band signal due to tolerances and drift of the transmitter frequency and of the mixing frequencies in the receiver is compensated by an automatic control. The signal converted to the base band is applied to a channel estimator which forms a channel estimation vector as an estimate of the instantaneous channel impulse responses in a complex bag band representation. A frequency deviation estimator evaluates the changes in time these channel estimation vectors.

摘要： A radio receiver for an RF signal which is phase or frequency modulated by an information signal. The receiver has an analog receiving section which provides non-linear dynamic compression. The resulting analog signal is sampled and the samples are digitized by an A/D converter. The non-linear dynamic compression reduces the necessary number of quantizing steps in the A/D converter, which is less expensive, but thereby introduces non-linear distortion. To compensate such distortion, in the digital processing section of the receiver an expansion section is provided which processes the digital signal samples in accordance with the inverse of the non-linear dynamic compression characteristic. The resulting expanded digital sample values equalize the analog non-linear dynamic compression. The information signal is recovered from the expanded digital signals.
