Claim 0:
1. A signal compensation method, comprising:
performing pre-equalization processing respectively on a plurality of bits corresponding to each modulation symbol in a bit sequence to be modulated, and adding results of the pre-equalization processing to obtain a first modulation symbol; and
performing nonlinear predistortion processing on the first modulation symbol to obtain a second modulation symbol,
wherein the pre-equalization processing is performed respectively on the bits corresponding to each modulation symbol, with respective equalization coefficients,
the method further comprises:
multiplying each equalization coefficient 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.
