An adaptive impulse noise canceler for digital subscriber lines

An adaptive impulse noise cancellation device is described. It is expected to substantially reduce the impact of impulse noise in asymmetrical digital subscriber lines (ADSLs) and will also benefit any digital transmission systems. It is capable of cancelling any of several different impulse shapes on a given loop, and the shapes can be learned by the device after it is installed. The canceler uses a relatively simple neuromorphic network
