  • The purpose of the paper is to optimize the pilot symbols in adaptive pilot symbols assisted coded modulation systems and to study the influences of the new algorithm on the whole system performances. A new algorithm is found to determine the interval of pilot symbols according to sampling theory and the second order statistics of fading channels. The partial measure and global measure are defined. The adaptation of the partial measure and the efficiency of the global measure are proved. It is also found that the global measure is a tighter and efficient interval bound.
