LOW COMPUTATIONAL ALGORITHM OF SOFT-DECISION EXTENDED BCH DECODING ALGORITHM FOR NEXT GENERATION DVB-RCS SYSTEMS

摘要

PURPOSE: A low computational amount soft-decision e-BCH decoding algorithm method for a next generation DVB-RCS system is provided to reduce computational amount by using distance difference between received data and the number of decoded test pattern, a scaling value and reliability. CONSTITUTION: A test pattern is generated through data of which reliability is below a predetermined reference value of the received data and the test pattern is arranged. e-BCH decoding is performed as many as the number of arranged test patterns. A received bit is searched using the received data and the decoded bit.
