## 5 Results and Discussion
### PRIME: Reed-Solomon Encoding  
Table 6 summarizes the results introducing Reed-Solomon as an outer encoder, additional to the convolutional encoding mechanism. Table 7 represents the incremental results compared to Table 4, which gathers the performance results for PRIME including the improved spline curve model for the equalizer. This way, the absolute and incremental results offer a more accurate idea of the physical improvement under study. \begin{table}
