A method and device for computing the multiplicative inverse of element x in Galois field GF(p) is proposed. In particular, when p is a prime number and m is an integer, the inverse may be constructed based on the observation that xis en element in sub-field GF(p) and the inverse of xcan be carried out in the sub-field. The inverse of X may be obtained by multiplying x=(x)by x.

Galois field computation

A communication system may include an equalizing device for DC-offset mitigation. The system includes: an input analog-to-digital converter configured to receive an input signal and produce a digital signal from the input signal; and a DC-offset estimation device coupled with the input analog-to-digital converter. The DC-offset estimation device is configured to produce a quantized DC-offset estimate from the digital signal. And the input analog-to-digital converter is configured to receive the quantized DC-offset estimate and to adjust a DC offset of the digital signal.
