Classification: CPC H | IPC H

Claim 4:
5. A signal compensation device, comprising:
a bit separation pre-equalization processing module and a nonlinear predistortion processing module;
wherein the bit separation pre-equalization processing module comprises a plurality of pre-equalization processors respectively corresponding to a plurality of bits corresponding to each modulation symbol, and a first adder;
the pre-equalization processors are configured to perform pre-equalization processing respectively on the bits corresponding to each modulation symbol in a bit sequence to be modulated;
the first adder is configured to add results of the pre-equalization processing to obtain a first modulation symbol; and
the nonlinear predistortion processing module is configured to perform nonlinear predistortion processing on the first modulation symbol to obtain a second modulation symbol,
wherein different pre-equalization processors have respective equalization coefficients, and
each of the pre-equalization processors is further configured to multiply the equalization coefficient of the pre-equalization processor by a preset weight value preconfigured according to an application scenario, to adjust a proportional relationship between the equalization coefficients according to the application scenario, thereby adjusting nonlinearity of an eye pattern of the first modulation symbol.
