[0035] Example 1
[0036] In this embodiment, a baseband signal is used to generate a multipath carrier phase error tracking signal to realize phase error estimation. See the schematic diagram of the phase error tracking signal generation circuit in the multipath signal carrier phase error estimation device figure 1 . It is mainly composed of the following parts: which includes an eleventh multiplier M for multiplying two baseband signals with multiple local PN sequences 11 , the twelfth multiplier M 12 , the thirteenth multiplier M 13 , the fourteenth multiplier M 14 , the fifteenth multiplier M 15 , the sixteenth multiplier M 16 , for the eleventh multiplier M respectively 11 , the twelfth multiplier M 12 , the thirteenth multiplier M 13 The eleventh processor 11, the twelfth processor 12, and the thirteenth processor 13 for processing the output baseband signal are used for the baseband signal output by the processors and the corresponding fourteenth multiplier M ...
