Method of transmitting and receiving data using precoding codebook in multi-user MIMO communication system and transmitter and receiver using the method
摘要：
Provided are a data transmitting and receiving method for a multiple-input multiple-output (MIMO) communication system, and a transmitter and a receiver using the method. Accordingly, since precoding matrices of a codebook is constituted using a rotation matrix, expansion of the codebook is easy, and since each of the precoding matrices is determined according to the number of transmit antennas, the codebook is systematically created according to a system. In addition the codebook can be applied to even a correlated channel, and the minimum distance between precoding matrices can advantageously be maximized.
摘要（中）：

提供了一种用于多输入多输出（MIMO）通信系统的数据发送和接收方法，以及使用该方法的发送器和接收器。 因此，由于使用旋转矩阵构成码本的预编码矩阵，因此码本的扩展容易，并且由于根据发送天线的数量来确定每个预编码矩阵，所以根据系统系统地创建码本。 此外，码本可以应用于甚至相关信道，并且预编码矩阵之间的最小距离可以有利地被最大化。
