Method and apapratus for processing data in multiple-input multiple-output (MIMO) communication system utilizing channel state information

MIMO系统中在接收机单元处"逐次"处理接收信号，并且根据MIMO信道可用的信道状态信息在接收机单元处"自适应地"地处理数据的技术。逐次对消接收机处理技术用于处理接收信号并且执行多次迭代以提供已解码的数据流。对于每次迭代而言，处理用于迭代的输入(如，接收到的)信号以提供一个或多个码元流。选择并处理码元流之一以提供已解码的数据流。由已解码数据流产生的干扰大致从被提供给下一次迭代的输入信号中被移去(即，消去)。信道特征被估计并被报告回发射机系统并且用于在传输前调整(即，适应)数据的处理(如，编码、调制等等)。 Techniques to 'successively' process received signals at a receiver unit in a MIMO system to recover transmitted data, and to 'adaptively' process data at a transmitter unit based on channel state information available for the MIMO channel. A successive cancellation receiver processing technique is used to process the received signals and performs a number of iterations to provide decoded data streams. For each iteration, input (e.g., received) signals for the iteration are processed to provide one or more symbol streams. One of the symbol streams is selected and processed to provide a decoded data stream. The interference due to the decoded data stream is approximately removed (i.e., canceled) from the input signals provided to the next iteration. The channel characteristics are estimated and reported back to the transmitter system and used to adjust (i.e., adapt) the processing (e.g., coding, modulation, and so on) of data prior to transmission.
