摘要:
A system for transmitting an n-level data signal (d k ) at a given symbol rate 1/T comprises a data transmitter (1), a transmission channel (2) and a data receiver (3) with an equalizer (30) of the decision feedback type. By arranging this equalizer (30) for forming an estimate ( c k ) of a virtual m-level data signal ( Ck ) instead of the output signal (b k ) of the data transmitter (1) error propagation in the equalizer (30) is considerably reduced without thereby appreciably adding to the implementation-complexity of the system.
