摘要： A method provided by the present invention for transmitting overhead information, includes dividing and reforming overhead information into at least two overhead parts, inserting the at least two overhead parts into overhead bytes of at least two corresponding data frames, and transmitting the at least two overhead parts via the it least two data frames which are microwave frames. Overhead information transmitting apparatus and overhead information receiving apparatus are also provided by the present invention. With the method and apparatus of the present invention, the channel bandwidth resources occupied by the overhead bytes or each microwave frame are greatly reduced. If the saved channel bandwidth is used for performing the error correction code on the transmitted information, the code gain is improved and the sensitivity requirement on the receiver is reduced so that the cost of a microwave transmitting system is reduced eventually.

摘要： An intermediate frequency receiving circuit and an intermediate frequency receiving method are provided. The intermediate frequency receiving circuit includes an inductor-capacitor (LC) resonance circuit whose primary resonance frequency is a central frequency of received signals. The LC resonance circuit receives intermediate frequency signals and suppresses transmitted signals and control signals. A band-pass filter connected to the LC resonance circuit filters the transmitted signals and control signals. An automatic gain control circuit connected to the band-pass filter compensates the attenuation of an intermediate frequency cable. A low-pass filter connected to the automatic gain control circuit compensates an in-band flatness. An analog-to-digital converter connected to the low-pass filter performs a sampling and digital demodulation on the received signals.
