Patent ID: 8301976

Claim:
A system comprising: a data detection module configured to receive input signals, detect data bits from the input signals; a reconstruction filter module configured to generate reconstructed signals using the data bits detected from the input signals; a first correlation module configured to correlate (i) the input signals and (ii) the reconstructed signals, and generate first correlation values based on the correlation of (i) the input signals and (ii) the reconstructed signals; and a second correlation module configured to self-correlate the reconstructed signals, and generate second correlation values based on the self-correlation of the reconstructed signals, wherein, in response to at least one of (i) the input signals and (ii) the reconstructed signals including a B-bit floating number having a sign bit, at least one of (i) the first correlation module and (ii) the second correlation module is configured to respectively generate (i) the first correlation values and (ii) the second correlation values based on the sign bit and K most significant bits (MSBs) of the B-bit floating number, wherein 0 K (B-I), and wherein B is an integer greater than 1.
