    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.

    摘要: This document is related to a method for receiving signals in multi-user system, the method comprising: receiving signals form 2 or more mobile stations using ‘k’-th radio resource and ‘k+m’-th radio resource; estimating a channel matrix using the received signals; calculating a weight matrix so that the channel matrix have an orthogonality to the signals from each of the mobile stations; transmitting the weight matrix to each of the mobile stations; and receiving signals that the weight matrix is applied by each of the mobile stations. By doing so, we can increase the transmission efficiency through obtaining both orthogonality and diversity gain in the multi-user MIMO system.
