Abstract
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.
