摘要： A method and apparatus for achieving China Mobile Multimedia Broadcasting (CMMB) diversity reception are disclosed. The method includes: acquiring respective Analogue-to-Digital Converter (ADC) data of two antennas; respectively conducting a synchronization and Fast Fourier Transform (FFT) operation on the ADC data of the two antennas, acquiring delay information about the two antennas, and according to an operation result, selecting a signal to noise ratio (SNR) configuration parameter; according to the delay information, conducting delay compensation on the operated data; and according to the selected SNR configuration parameter, merging the data of the two antennas on which the delay compensation is conducted, and outputting the data. The method and apparatus are able to acquire a signal with extremely small interference and acquire a higher mobile performance.
