Patent ID: 6839381

Claim:
A method of obtaining an estimate of digital information contained in an input signal having pilot information and attached to a carrier signal, comprising the steps of: processing the input signal to obtain a plurality of pilot symbols in complex base band coordinates representative of the pilot information; obtaining complex arguments of the pilot symbols using an arctangent function; using linear least squares methodology applied to the complex arguments to obtain frequency correction information and phase correction information; using the phase correction information and frequency correction information to obtain the estimate of the digital information; wherein the pilot symbols include noise and wherein the step of using linear least squares further comprises: using predictor-corrector methodology to obtain estimated complex arguments of the pilot symbols without the noise, wherein each estimated complex argument corresponds to a complex argument; wherein the step of using linear squares further comprises arranging the plurality of complex arguments in sequential order; wherein the step of using predictor-corrector methodology further comprises sequentially obtaining each estimated complex argument; and wherein the step of using predictor-corrector methodology further comprises comparing a difference between each complex argument and its corresponding estimated complex argument to a first predetermined value.
