A device for placing power control data in a transmission signal has: a generating device for generating power control data as a function of a received signal, a buffer for buffering a formatted transmission data word that contains a power control data field for recording power control data, an inserting device for inserting the generated power control data into the power control data field of the buffered transmission data word, and a modulation device for modulating the transmission data word to form a transmission signal with a transmission power corresponding to the power control data.

An apparatus for finely synchronizing code signals with an encoded received signal includes a sampling device for sampling the received signal at regular sampling intervals, a pulse shaper for shaping the sampled received signal pulses in order to output a first and second pulse-shaped sample in dependence on an autocorrelation function, a buffer for buffering the two samples, a code signal generator for generating the code signal, correlation devices for correlating the generated code with the two buffered samples to form two correlation values, and an interpolation device for forming an interpolation value as a function of the two pulse-shaped samples and the deviation between the two correlation values.

A code word generator for OVSF codes, comprising an intermediate memory device ( ) which is used to input a calculation index as a binary calculation index data word, a calculation device ( ) which permutes the significant data bits of the calculation index data word bit-by-bit so that a calculation basis (B) can be generated, a counter ( ) for producing a counting variable (Z) and provided with a logic circuit comprising several AND gates for bit-by-bit linkage of the counting variables (Z) generated with the calculation basis (B) in order to form a linking data word and several XOR gates for logical reduction of the linking data word to form code word data bits of the OVSF code word.
