Abstract:
The invention relates to a method, a computer program product and a device for evaluating a code which is orthogonal to one or more further codes. The method comprises the steps of receiving a signal which carries a code containing a sequence of code symbols, determining for a particular symbol instant at least one channel estimate, determining for the particular symbol instant a compensation value taking into account the at least one channel estimate, compensating each code symbol using the compensation value determined for the corresponding symbol instant, wherein the compensation is performed such that an original power relationship among the individual code symbols contained in the code is restored, and evaluating the code on the basis of the sequence of compensated code symbols exploiting the orthogonality to further codes.
