Abstract: The present invention provides a method and modem for adjusting a modulation mode. In embodiments of the present invention, a first modem generates indication information according to a current working first modulation mode, so that the first modem can send the indication information to a second modem through a data frame. Therefore, the second modem adjusts a current working second modulation mode of the second modem according to the indication information, so that the adjusted second modulation mode is consistent with the first modulation mode. Therefore, the problem of complex operations in the prior art, caused by that an operator configures a modulation mode of a second modem as a current working modulation mode of a peer modem, that is, a first modem, can be avoided, and efficiency of network deployment can be improved.

Abstract: The present invention provides a phase jump detection method, apparatus, and system. In embodiments of the present invention, by collecting N frequency control words, a phase jump in an intermediate frequency signal is detected according to the N frequency control words. An extra phase jump meter is not required, and therefore detection may be supported on massive microwave communication devices, thereby improving the detection efficiency.
