Abstract: There is provided an address generation apparatus for one of an interleaver and a deinterleaver in a Wideband Code Division Multiple Access (W-CDMA) system. The apparatus includes an address pair generator for generating an address pair (n, P(n)) in real-time for one of an interleaver operation and a deinterleaver operation that includes inter-row permutation and intra-row permutation.

Further, the address pair (n, P(n)) is generated such that, for the deinterleaving operation, data to be deinterleaved are read out from the at least one memory device using the n and deinterleaved data are written into the at least one memory device using the P(n).

Abstract: When an optical recording medium having a plurality of data layers is being read from and/or written to, the input beam experiences an aberration, inter alia in the top layers of the data layers. In order, nevertheless, to achieve a high data density, a device for correcting the spherical aberration is located in the beam path of the input beam. In the case of the use of an optical diode in which the input beam and the reflected beam have directions of polarization perpendicular to one another, such a device is expensive to implement and associated with a reduced optical efficiency. It is an object of the invention to propose an apparatus for reading from and/or writing to optical recording media, in the case of which a high optical efficiency and balancing of the spherical aberration are achieved with low outlay.

Abstract: Progressive rounding error and convergence error encountered due to multiple use of a center correction adjustment of an image of a video projection display is reduced by calculating a 3×3 matrix for a moved color signal where the non center matrix values represent the difference between the initially measured sensor values stored at initial alignment, and stored most recently measured sensor values. The matrix center value is the sum of the averaged values calculated from the edge center errors, the stored sum of previous moves and the current move. Rerun of the sensor finding routine resets the stored move sum to zero.

Abstract: So-called LCH packets are defined in the Hiperlan Type 2 System for wire-free transmission of video and audio data streams. These LCH packets have a length of 54 data bytes. Furthermore, the Hiperlan/2 Standard provides for so-called ARQ messages to be sent back to the transmitter in an SCH packet in a QOS mode (Quality Of Service), in which all the LCH data packets must be confirmed by the receiver. Space for the LCH and SCH data packets must be provided in a buffer store in the Hiperlan/2 interface for each connection that is set up. When there is a possibility of several hundred connections having been set up, separate reservation of memory areas for LCH and SCH packets would involve considerable complexity for the memory organization. The invention proposes that only one common area be reserved for LCH and SCH packets in the buffer store. The section which is provided for each LCH package is of such a size that it corresponds to a value 2n where n?[0, 1, 2, 3, . . .
