摘要： Disclosed is a spectrum spread communication system which is hardly influenced by noises, and in which a frame structure can be identified at a receiving side without use of a frame synchronization signal. A spread code generator switches spread codes (“Scai” and “Scbi”) in each frame, and outputs it to a spread modulation unit. The spread modulation unit performs spread modulation of transmission data, and transmits it to a direct current power line. A reference code generator generates reference codes (“Scai” and “Scbi”) in the same code phase. Spread demodulation units performs spread demodulation of the received signal with use of the reference codes (“Scai” and “Scbi”), and output it to a selection unit. A frame synchronization detection unit identifies a frame structure on the basis of switching of a synchronization state of a code phase in a code phase synchronization detection unit. The selection unit outputs reception data by selecting spread demodulated data from the spread demodulation unit which is in a phase-synchronized state.

摘要： A data compression method uses a template. In the template, the template optimizing is performed by an artificial intelligent technique (such as a genetic algorithm). The artificial intelligent techniqiue is applied to segments defined by diving input data into uniform segment units. The compression method contributes to enhancing the prediction accuracy. The data is compressed using the results of optimization, and a database is updated to improve the compression efficiency and speed of the subsequent processings. By updating a database by using an optimized template, a template for improving the prediction accuracy is obtained quickly without applying any artificial intelligent technique.
