    • A method and apparatus for controlling a multi-input multi-output (MIMO) radio frequency (RF) transceiver having a plurality of RF blocks using a single serial programming interface (SPI) are provided. The MIMO system includes: a MIMO transceiver, having one or more input and output units and a serial interface conversion unit controlling the input and output units; and a controller, which controls the MIMO transceiver. The serial interface conversion unit receives control data from the controller via a serial programming interface (SPI), decodes the received control data to have a format appropriate for controlling the input and output units, and encodes data received from the input and output units to be compatible with the SPI. Accordingly, it is possible to realize a small-sized MIMO system having a simple structure and to reduce the probability of errors occurring in the process of controlling a plurality of RF blocks of the MIMO system.
    • 提供了一种用于使用单个串行编程接口(SPI)来控制具有多个RF块的多输入多输出(MIMO)射频(RF)收发器的方法和装置。 MIMO系统包括:具有一个或多个输入和输出单元的MIMO收发器和控制输入和输出单元的串行接口转换单元; 以及控制MIMO收发器的控制器。 串行接口转换单元通过串行编程接口(SPI)从控制器接收控制数据,将接收到的控制数据解码为具有适合于控制输入和输出单元的格式,并将从输入和输出单元接收的数据编码为 与SPI兼容。 因此,可以实现具有简单结构的小型MIMO系统,并且在控制MIMO系统的多个RF块的过程中减少错误发生的概率。
