COMMUNICATION SYSTEM BASED SPREADING CODE WITH ZERO CORRELATION DURATION AND PROCESSING METHOD THEREOF, AND RECORDING MEDIUM THEREOF

摘要

A method for generating a new spreading code having a characteristic of zero correlation intervals continuously for a predetermined time interval, and an internal power line communication system using a CDMA modulation / demodulation method based on the spreading coding method, and a communication processing method thereof The present invention relates to a computer-readable recording medium having recorded thereon a program for executing a program. The spreading code-based internal power line communication system converts binary spreading code signals having a zero-correlation characteristic continuously over a period of time. A transmitter including a spreading code generator having a zero correlation interval characteristic, and a receiver including a matched filter unit performing a correlation process on a binary spread code pattern having a zero correlation interval characteristic continuously for a predetermined time interval to derive an autocorrelation peak value. And a signal transmitted from the transmitter to the receiver To provide a configuration including a power line channel to output.;By using a spreading code-based indoor power line communication system having the above characteristics, an internal power line communication processing method, and a recording medium recording the same, impulsive noise or multipath interference (MPI) caused by various load variations are inherent. It can overcome the poor power line channel environment.; Impulse, various load fluctuations, multipath interference, power line, channel environment
