Abstract: An anti-counterfeit device with dynamic barcodes is disclosed. An anti-counterfeit system with dynamic barcodes provides an anti-counterfeit mechanism when a user uses an electronic value barcode. The anti-counterfeit device includes a barcode generator module, an anti-counterfeit generator module and a combination module. The barcode generator module generates electronic barcodes that can be read directly by a barcode reader. The anti-counterfeit generator module generates dynamic anti-counterfeit labels with dynamic exchange information varying in time.

Abstract: 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.

Abstract: In one aspect, a method for mitigating an effect of an interfering radio signal at a multiple antenna receiver includes forming an estimate of a relationship of the interfering signal among signals received from the multiple antennas. In general, the interfering signal does not share the same communication technology as a desired signal. The signals received from the multiple antennas filtered and combined according to the estimate of the relationship of the interfering channels to reduce an effect of the interfering signal. Desired data present in the desired signal represented in the filtered and combined signals is decoded and the estimate of the relationship of the interfering signals is updated according to the decoding of the desired signal.
