DATA SLICING USING N PREVIOUSLY DECODED SYMBOLS

摘要

Data slicer comprising a threshold generating device (8) which generates an analogue threshold signal; and a comparator device (3) having a signal input (4) which receives the signal to be decoded, a threshold input (5, 6) which receives the threshold signal, and an output (7). The comparator device (3) compares the demodulated signal with the result of the comparison, each digital signal representing a respective digital symbol, and wherein the threshold signal generated by the threshold generating device is determined in accordance with the N previously generated digital signals. The invention may also provide a timing device (18) and an amplitude measuring device (24), both of them being responsive in accordance with the N previously generated digital signals.
