Detailed Description
SatChannelEstimatorError reads from file and stores the channel estimation error mean and standard deviation values for a set of SINR values.
Channel estimation error mean and standard deviation is dependent on calculated SINR. A proper error for a given SINR is interpolated between two closest SINR points. The channel estimation error is added to a given measurement by using the AddError method.
