摘要：
The present invention provides a pre-emphasis selection method, digital signal processing module and digital communication system that use computations based on channel spectrum measurements for efficient, non-complex determination of a pre-emphasis filter index. By avoiding the complex computations, a near optimal selection of a pre-emphasis filter with robust performance is achieved with relatively simple calculations.
