Dispersion compensation using digital infinite impulse response filtering |
摘要 |
Methods and systems for novel infinite impulse response filtering system to allow DC using a complex input signal having a real and imaginary part of the complex input signal yr and yi to produce a real part of a dispersion-compensated signal Xr. The system includes a first filtering circuit for filtering the real part of the input signal yr to produce a filtered real signal w1, a second filtering circuit for filtering and time reversing the imaginary part of an input signal yi to produce a filtered imaginary signal, and a first output summing device for summing the real and the imaginary filtered signal to produce the real part of a dispersion-compensated signal Xr. In an embodiment the filtering is accomplished with time reversing devices and real coefficient infinite impulse filters. In another embodiment, the filtering is accomplished with complex-coefficient infinite impulse filters. |
