Abstract

Embodiments provide a data receiver, the data receiver being configured to receive a signal including a sequence of N bits so as to obtain a reception signal, wherein N is a natural number greater than or equal to eight, N≥8, wherein the data receiver is configured to sample the reception signal with a sampling rate that corresponds, with an intentional deviation of up to 2/N, to one sample value per bit of the sequence of N bits so as to obtain a sequence of received bits, wherein the data receiver is configured to correlate the sequence of received bits with K different sequences of N-1 reference bits so as to obtain K partial correlation results, wherein K is smaller than or equal to N-1 and greater than or equal to three, N-1≥K≥3.
