Abstract：
The invention discloses a mixed baseband system for high speed communication, comprising a modulus carrier recovering module which comprises a phase rotator, is connected to the output of a high speed communication system and is used for receiving signals demodulated by the high speed communication system and removing the influence of carrier deviation on the signals through recovering the phase of a sender; a data feedback equalizing module which is connected to the modulus carrier recovering module and is used for equalizing the signals output by the modulus carrier recovering module so as to reduce the influence of intersymbol interference and further increase the Signal to Noise Ratio; a clock and data covering module which is connected to the data feedback equalizing module and is used for recovering a clock and demodulating the signals output by the data feedback equalizing module so as to obtain and output finally demodulated signals. Compared with the prior art, the system of the invention simplifies the baseband design of a receiver and saves power consumption on the premise of ensuring signal transmission processing precision and accuracy.
