Abstract: To improve the recognition of the validity of coded control information that is transmitted, together with associated useful data, as a data signal and that is decoded at the receiver by means of a Viterbi decoder (VDCOD), it is proposed that at least an end section of the received, convolution-coded control information is prefixed to this same information, the length of the end section being at least that of the convolution-coded tail bit-sequence, and the information that has been assembled in this way being fed to the Viterbi decoder to allow the convolution-coded control information to be decoded.

Abstract: The present invention provides a method for generating soft bit information from Gray coded signals. By using Gray coding, soft bit information is generated for each bit by performing simple absolute value generation and substraction. Prior to the actual soft bit calculation, a complex received symbol Y (Y=S.H+N) is multiplied by a complex conjugate H* of a channel transfer function H to provide a received symbol (R=S./H/2+NH*) corrected for phase and weighted for the channel amplitude. Thereafter, the soft bit information (D(R,S)1) for the in-phase and quadrature components of an m-valued QAM signal is calculated.

Abstract: The invention relates to a method for configuring a memory with I/O support. The aim of the invention is to guarantee the processor and 110 functional units that function in time-critical conditions the appropriate priority for data access, using simple programmes. To this end, an input memory area which the 110 unit can only write into and which the processor unit can only read out of and an output memory area which the 110 unit can only read out of and which the processor unit can only write into are specified in the processor.

Abstract: The invention relates to a method for receiving spread-spectrum signals for fine time synchronization of correlators in a RAKE receiver. The objective of the invention is to produce a signal that is to be transmitted with the highest possible signal to noise ratio on the basis of the received signal. To achieve this, a higher level unit intervenes in the normal adjustment of a first basic time lag in a first RAKE finger and the normal adjustment of a second basic time lag in a second RAKE finger when the difference between the basic time lags of both RAKE fingers corresponds to a minimum level, and subsequently carries out a joint adjustment for both RAKE fingers, taking time error estimates for both RAKE fingers into account.
