ADAPTIVE LINE EQUALIZER FOR IMPROVING DATA COMMUNICATION OVER LESS THAN PERFECT POWER LINES OR TRANSMISSION LINES |
摘要 |
Systems and methods for improving data communication over less than perfect power lines or transmission lines are described. The systems and methods allow for pushing out electrically any null within a frequency range of interest and/or for lossless transmission by providing impedance matching between communication devices and the transmission line. This is achieved by implementing line equalizing modules within the transceivers, at the transmitter side and/or the receiver side, or by plugging, as a stand-alone module, into an electrical outlet within a building. The line equalizing module includes multiple inductor-capacitor cells coupled in cascade where multiple switches allow for selective and concurrent connection between the inductor-capacitor cells. In another embodiment, the line equalizing module includes variable inductor-capacitor cells. The line equalizing module provides a variable propagation delay that allows for stretching electrically the transmission line. Further improvement may achieve by adjusting the operational frequency using an up-conversion or down-conversion operation. |

1. A line equalizing module for improving analog, digital, and radio frequency (RF) transmission over various types of transmission mediums, the line equalizing module comprises:
a plurality of inductors coupled in series or in parallel; a plurality of capacitors, each capacitor is coupled to one inductor from the plurality of inductors to form an inductor-capacitor cell; a plurality of switches for providing selective and concurrent connection between a plurality of cascaded inductor-capacitor cells so as to provide a variable propagation delay allowing to stretch electrically a transmission line. |
