Title: Apparatus for recovering carrier
Inventor: JUN JEONG SIK
IPC: H04L27/16
Filed: 2002-12-30
Abstract: PURPOSE: A carrier wave recovering device is provided to utilize carrier wave pilot signals and received all data signals simultaneously even though frequency components corresponding to carrier wave signal components are completely removed by serious linear noise. CONSTITUTION: A carrier wave recovering device includes a phase splitter, first and second complex multipliers, first and second squarers and a subtracter, a band pass filter, a Gardner phase error detector, a loop filter and an oscillator. The phase splitter(603)separates phases of pass band signals digitalized by a fixed frequency. The first complex multiplier(604) complex-multiplies a phase-split real signal and a quadrature signal by demultiplexing carrier waves proportional to a phase error to deform the signals to two base band signals {i(t),q(t)}. The second complex multiplier(607) outputs two like offset QAM(Quadrature Amplitude Modulated) signals {i'(t),q'(t)} by the base band signals. The first and second squarers(609,610) non-linearly operate the like offset QAM signals and the subtracter(611) subtracts outputs from the first and second squarers from each other. The band pass filter(612) extracts components corresponding to carrier wave frequencies from the output of the subtracter. The Gardner phase error detector(613) detects a phase error of the filtered signals. The loop filter(614) carries out low band pass for outputs from the Gardner phase error detector, and outputs the filtered outputs to the oscillator(605) for carrier wave recovering.
