METHOD FOR CONDUCTING FREQUENCY DOMAIN INFORMATION EXPANSION ON DATA SYMBOL IN POWER LINE CARRIER COMMUNICATION

摘要

A method for conducting frequency domain information expansion on a data symbol in power line carrier communication. When a data symbol is generated in power line carrier communication, multiple instances of frequency domain information diversity expansion are used to replace original ROBO expansion; the diversity expansion is unrelated to the time-varying property of a channel, and is only related to the features of the channel; and the diversity expansion is completed in one symbol, this being beneficial to simplifying processing circuits in a frequency domain, and also improving communication reliability.
