Embodiment Construction

[0024] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only to facilitate description of the present invention and has no specific meaning by itself. Therefore, 'module', 'part' or 'unit' may be used in combination.

[0026] As mentioned above in the technical background, the conventional signal processing device for amplifying signals has the problem of low power amplifier efficiency in the process of processing baseband signals of at least one frequency to obtain amplified signals. The reason is that in the prior art, the signal processing device first decomposes the baseband signal to obtain the decomposed signal, and then outputs the amplified analog signal through the dual-frequency power amplifier, and then changes the amplitude and / or phase of the baseba...

Abstract

The invention discloses a signal processing device and method. The signal processing device comprises a baseband signal input module, a signal separation module, a signal modulation module and a dual-band power amplifier, the baseband signal input module is used for inputting N kinds of baseband signals; the signal separation module comprises K1 first signal separation units and K2 second signal separation units; the first signal separation unit is used for changing the parameters of the (Ni) th baseband signal according to the variation determined by the module value of the comprehensive baseband signal to obtain two decomposed signals; the second signal separation unit is used for changing the parameters of the Nj-th baseband signal according to the inherent variation to obtain two decomposition signals; and when K1 is 0 or K2 is 0, the signal processing device further comprises a channel performance compensation module used for compensating the difference generated by the discrete device on the parameters of the decomposed signal. According to the technical scheme, the signal processing device with high power amplification efficiency can be realized.

Description
