Aliasing effect compensation method for bidirectional data transmission pre-calculating compensation signal using aliasing prediction filter and adding compensation signal to information signal

摘要

The method involves pre-calculating a compensation signal (14) on the basis of a data signal (15) in a first transmission unit and echo behavior of a bidirectional data transmission. The compensation signal is added to the information signal (16) of a second transmission unit. The compensation signal is generated by an aliasing prediction filter (13), which imitates the behavior of the bidirectional data transmission between a tapping point (17) and the addition point (18) of the data signal for the pre-calculation. An Independent claim is also included for a compensation unit for a bidirectional data transmission having an aliasing prediction filter.
