  • Patent number: 7054351
    Abstract: In order to control memory accesses in RAKE receivers having early-late tracking in telecommunications systems with wire-free telecommunication between mobile and/or stationary transmitters/receivers, in particular in third-generation mobile radio systems, such that the number of memory accesses is less than with previous known methods, data which is received in the RAKE receiver and is read by an early finger in the early-late tracking is buffer-stored and is passed on one read cycle later to a late finger for reading by the same in the early-late tracking.

  • Patent number: 7031737
    Abstract: To improve a rake receiver for telecommunication systems with wireless telecommunication between mobile and/or stationary transceivers, especially in third-generation mobile radio systems, compared with known rake receivers, such that savings with respect to the number of function blocks and logic gates used are possible, a pipeline architecture is provided in which the individual computing steps are processed as on a pipeline.

  • Patent number: 6690312
    Abstract: For regulating the signal level fed to an analog/digital converter, the rate of change at which the output signal of the analog/digital converter changes over time, in particular the rate of change of an output bit of the analog/digital converter, is measured and compared with a setpoint value, in order to set the signal level fed to the analog/digital converter based on the comparison.

  • Patent number: 6526428
    Abstract: A method and apparatus determines interpolated intermediated values of a sampled signal. In order to determine interpolated intermediate values of a sampled signal, such as a digital mobile radio signal, the parameters a, b and c of the second-order polynomial y=ax2+bx+c are determined starting from three known sample values (x1, y1), (x2, y2) and (x3, y3), so that intermediate values can be calculated using the polynomial. Here it is assumed that the signal is sampled at constant intervals, in particular at intervals normalized to d=1, and the center sample value is assigned to the sampling instant x2=0, by which, a calculation can be carried out with low hardware complexity.
