Claim 7:
8. Data receiver, comprising:
a sampler,
a correlator, and
a detector,
wherein the data receiver is configured to receive an OOK-modulated signal comprising a sequence of 31 bits so as to acquire a reception signal,
wherein the sampler is configured to sample the reception signal with a sampling rate that corresponds, with an intentional deviation of up to 7%, to one sample value per bit of the sequence of 31 bits so as to acquire a sequence of received bits,
wherein the correlator is configured to correlate the sequence of received bits with 5 different sequences of 30 reference bits so as to acquire 5 partial correlation results,
wherein the 5 different sequences of reference bits are differently punctured versions of the same base sequence of 31 reference bits,
wherein the data receiver detector is configured to detect the sequence of 31 bits if at least one of the 5 partial correlation results exceeds a detection threshold.
