摘要： In a method for communication, first and second signals for timing synchronization are generated. Frequencies of the first and second signals are converted to other frequencies to obtain a first and second RF signals, which have a specific frequency gap therebetween. The first and second RF signals are combined to obtain a transmission signal, and the transmission signal is transmitted. When the transmission signal is received as a received signal, the frequency of the received signal is shifted by the specific frequency gap to obtain a converted signal. A complex conjugation of the converted signal calculated to obtain a complex conjugation signal. The received signal and the complex conjugation signal are multiplied to obtain a multiplication signal to calculate cross-correlation between a product of the first and second signals and the multiplication signal. A peak of the cross-correlation is detected to set a base time for timing synchronization.
