Abstract
There are disclosed systems and methods of determining a fault location on a wire. In an embodiment, a system includes a PN code having a chip-time. Software code is provided for delaying the PN code a series of delays to form delayed PN samples, a sum of the series of delays being less than one chip-time. Software code is provided for summing the delayed PN samples with the PN code to form a summed sequence. Software code is provided for transmitting the summed PN sequence to the wire. Software code is provided for receiving a signal from the wire related to the summed PN sequence. Software code is provided for mixing the signal received from the wire with a delayed copy of the summed PN sequence so as to form a mixed signal. Software code is provided for integrating the mixed signal to map faults. Other embodiments are also disclosed.
