Digital broadcasting transmission/reception capable of improving receiving and equalizing performance and signal processing method thereof

Abstract From the Canadian patent

A digital broadcast transmitting and receiving system and a signal proccesing method thereof that improves the receiving performance of the system. A digital broadcast transmitter can include a randomizer to receive and randomize a data stream into a specified position of which stuff bytes are inserted, a replacement sequence generator to generate known data consisting of a predefined sequence, a stuff-byte exchange unit to insert the known data into the specified position of the data stream into which the stuff bytes are inserted, an encoder to encode the data stream output from the stuff-byte exchange unit for an error correction, and a transmission unit to modulate the encoded …
