Abstract
The determination of the signal modulation format for a channel is an important aspect of the operation of a signal receiver. A method () is described including the steps of receiving () a signal, comparing () a sample of the received signal to a first threshold value and a second threshold value, creating () a signal profile based on the comparison, and selecting () a modulation format for the received signal based on the signal profile. An apparatus () is also described including a ring counter () that receives a sample of an input signal, compares the sample to a first threshold value and a second threshold value, and creates a signal profile for the input signal, a signal profiler () that compares the signal profile for the input signal to at least two reference profiles, and a detector () that determines a modulation format for the input signal based on the comparison in the signal profiler ().
