For avoiding error propagation as a result of decision feedback equalization, the data to be transmitted are coded with a coder 2 which has a transfer function substantially inverse to the transfer function of the channel 4. Consequently, instantaneous decisions about the received symbol may be made...http://www.google.com/patents/US5353310?utm_source=gb-gplus-sharePatent US5353310 - Data transmission system with reduced error propagation
