Methods and devices for "shaping" a slope of the phase component of OFDM data symbols in order to decrease an accumulation of phase error are provided. By way of example, a method 100 includes receiving an incoming data signal via a processor 12 of a transmitter 28. The method 100 further includes computing one or more roots of a first function representing a phase component of the data signal, computing a second function representing the phase component based on the one or more roots, deriving a periodicity of the phase component based on the second function, and deriving a value of a slope of the phase component based at least in part on the periodicity of the phase component to reduce or eliminate an error of the phase component. |
