Receiving data over channels with intersymbol interference

An apparatus for receiving data, the apparatus comprising:

• means for sampling the data at data sampling points to obtain data samples;
• means for sampling the data at intermediate sampling points between the data sampling points to obtain intermediate samples;
• and
• means for correcting the data at at least one intermediate sampling point of the intermediate sampling points depending on at least one of a previous data sample sampled at a data sampling point preceding the at least one intermediate sampling point and a previous intermediate sample sampled at an intermediate sampling point preceding the at least one intermediate sampling point.

An apparatus configured to receive data, the apparatus comprising:

• a data input;
• a first sampling unit clocked by a data sampling clock operatively connected to the data input and configured to sample data fed to the data input at data sampling points determined by the data sampling clock to generate data samples;
• a second sampling unit clocked by an intermediate sampling clock operatively connected to the data input and configured to sample data fed to the data input at intermediate sampling points determined by the intermediate sampling clock;
• a calculating unit operatively connected to at least one of the first sampling unit and the second sampling unit and configured to calculate an intermediate correction signal;
• and
• an adder operatively connected to the data input and to the calculating unit and configured to add the intermediate correction signal to the data for correcting the data at the intermediate sampling points.
