Abstract:
1. A method comprising the steps of: receiving a signal containing a plurality of channels; filtering the received signal, the step of filtering including using only one band edge filter; determining if the filtered signal includes an indicator of a first band edge of a channel, the indicator being represented by a signal generated by processing the filtered received signal; determining a characteristic of the channel based on the indicator of the band edge of the channel if the filtered signal includes the indicator, the characteristic being a symbol rate of the channel, the step of determining the characteristic further using adaptive line enhancement to determine the frequency location of the indicator of the first band edge of the channel with an output from the adaptive line enhancement used to determine the characteristic of the channel; and estimating a frequency for the location of a second band edge of the channel using the frequency location of the indicator of the first band edge and the characteristic of the channel.
