Improved link to system interfacing methodology for exponential effective SNR mapping using enhanced lookup tables

Link to system interface methodology is a technique used in system level simulations to predict the receiver behavior using lookup tables under different channel conditions. This paper presents an improvement in link to system interfacing methodology for exponential effective signal to noise ratio mapping for a single input and single output transmission mode. It is proposed that the mean value of the receiver performance measure for different channels be used as reference instead of the performance of a single line of sight link. The results show a considerable improvement in the mean square error between the predicted and observed frame error rates at different signal to noise ratios.
