摘要： A signal transmission method for use in a multi-antenna system includes: receiving a complex signal using N antennas and M timeslots as a single unit, and generating a space-time code (STC) for performing interleaving and phase-shifting operations of the received complex signal; and applying the space-time code (STC) to the received complex signal, and transmitting the resultant signal. Therefore, the signal transmission method provides a space-time code (STC) provides a space-time code (STC) having higher performance and lower encoding complexity, and can effectively transmit the signal via the multi-antenna system.
