Reception terminal and a method for compensating inter-symbol interference and computer readable recording medium for performing the same

A reception terminal for compensating inter-symbol interference (ISI) in a two-dimensional (2D) data structure, the reception terminal comprising:

• a processor,
• wherein the processor receives a plurality of pixel values for compensation based on a 2D data structure for compensation via a channel and compensates each of the plurality of pixel values for compensation to each of pixel values after compensation, respectively,
• wherein the plurality of pixel values for compensation are a distorted set of values of a plurality of source pixel values due to the ISI, and
• wherein each of the pixel values after compensation is determined based on each of the plurality of pixel values for compensation and adjacent pixel values thereof, wherein each of the pixel values after compensation is determined according to a following equation 1
• I′(m,n)=I(m,n)−Δ(I(m−1,n−1)+I(m−1,n)+I(m−1,n+1)+I(m,n−1)+I(m,n−1)+I(m+1,n−1)+I(m+1,n)+I(m+1,n+1) [Equation 1]
• where I′(m,n) denotes the pixel values after compensation at a position (m, n),
• I(m,n) denotes one of the plurality of pixel values for compensation at a position (m, n),
• each of
• I(m−1,n−1), I(m−1,n), I(m−1,n+1), I(m,n−1), I(m,n−1), I(m−1,n−1), I(m+1,n), I(m+1,n+1) denotes each of the adjacent pixel values, and Δ denotes a weight value.
