摘要： Modern coding and modulation techniques have greatly improved the transmission of signals. A method is described including receiving a stream of data bits, demultiplexing the stream into a first and second substream, encoding the first and second substream using a low density parity check coding process, and mapping the first substream to a first region of a symbol constellation map and the second substream to a second region. Also, an apparatus is described including a demultiplexer that produces a first and second bitstream, a first encoder that encodes the first substream using a low density parity check coding process at a first encoding rate, a second encoder that encodes the second substream at a second rate, and a symbol mapper that maps bits from the first substream to a first region of a symbol constellation map and maps bits from the second substream to a second region.

摘要： A method, system, and apparatus for diagnosing a route in a network based on a Diameter protocol are provided. The method includes the following steps. A source Diameter node generates a diagnosis message and sends it. An intermediate Diameter node adds diagnosis information thereof to the diagnosis message after receiving it and forwards it until the diagnosis message is forwarded to a Diameter server capable of processing the diagnosis message or a Diameter node incapable of forwarding the diagnosis message. The Diameter server or the Diameter node generates a response message and sends it carrying diagnosis information thereof, information in the diagnosis message, and a response type. The intermediate Diameter node adds the diagnosis information thereof to the response message after receiving it, and forwards it until the response message is forwarded to the source Diameter node. The source Diameter node parses the response message to obtain route related information.
