linear interpolation

Linear interpolation is a method useful for curve fitting using linear polynomials.

It helps in building new data points within the range of a discrete set of already known data points.

Therefore, the Linear interpolation is the simplest method for estimating a channel from the vector of the given channel's estimates.[1]
