Abstract: In a method, device and digital receiver for transmitting signals in magnetic resonance imaging, M channels of digital signals are received over M receiving channels from a digital matrix processor. One receiving channel corresponds to one channel of digital signal and the M channels of digital signals include one channel of main signal and (M?1) channels of high-order signals. The M channels of digital signals are combined into N channels of combined signals, wherein the main signal and at least one channel of high-order signal are combined into one channel of combined signal, or at least two channels of high-order signals are combined into one channel of combined signal. N and M are both positive integers, N is less than M, and M is greater than or equal to 2.
