Methods and systems are provided in which a network induces different distortions in signals traversing different segments of the network. The distortions may be used to identify locations on the network of devices that transmit and receive the signals. The distortions may be reflected in equalization coefficients programmed into transmitting or receiving devices, which may be used to pre or post filter the signals to compensate for the distortions.

Inducing response signatures in a communication network

System and methods for inferring network topology are described, including a method comprising determining a normalized transmit power of a first device, identifying a second device based upon a parameter of the second device and the normalized transmit power of the first device, and generating a topology including the first device and the second device based upon at least one of the normalized transmit power of the first device and the parameter of the second device.
