Embodiment Construction
[0032] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] figure 1 It is the overall flow chart of the implementation of the line width compensation module method applied to the DQPSK system of the present invention. The line width compensation module includes: a data preprocessing module 101, a phase calculation module 102 of orthogonal data, a phase precompensation module 103, a residual The phase offset calculation module 104, the residual phase compensation module 105, and the phase precompensation amount updating module 106, this method can be implemented by a digital chip, which can be a DSP or FPGA chip.
[0034] The following modules are set in the digital processing chip: In the digital chip, the data is transmitted in parallel, and the data transmission adopts the grouping of vector signal data in chronological order, and each group includes N continuous data entering the preprocessin...
