  • Publication number: 20040076249
    Abstract: This process has the objective to eliminate the problem of intersymbol interference in digital signals, which is caused by the dispersive effect of any practical transmission channel. The solution for the problem of superposition of propagation rays and its dynamic variation in the transmission channel of a digital system will be one of the hardest challenges for the technological improvement in this area for the next few years. In mobile communications, this undesirable phenomena is characterized by parameters such as delay spread, angle spread and Doppler spread, which determine the level and dynamics of superposition between the system symbols, occurring as a consequence of the transmission of information through the channel. The devices that are likely to have their performance improved by the use of the Concurrent Process for Blind Deconvolution of Digital Signals includes but is not limited to: Spatial-Temporal Processing (used, for example, in Smart Antennas; Smart Sensors, etc . . .
