    • The present invention provides a method for transmitting and receiving data in a single carrier frequency division multiple access system to which a precoding matrix is applied, and to a transmitting / receiving apparatus for same. The method for transmitting data comprises the steps of: applying selected mapping algorithm (SLM) sequences of an SLM sequence subset corresponding to a precoding matrix, to respective data; selecting the SLM sequence in which each of the applied data has the smallest peak to average power ratio (PAPR) value; and transmitting the index of the selected SLM sequence and data to which the selected SLM sequence is applied. The method for receiving data, to which a precoding matrix is applied, comprises the steps of: receiving the index of the SLM sequence selected from the SLM sequence subset corresponding to the precoding matrix, and data to which the selected SLM sequence is applied; and removing the SLM sequence from the data to which the SLM sequence is applied using the SLM sequence indicated by the index, in order to recover data.
    • 本发明提供一种用于在应用了预编码矩阵的单载波频分多址系统中发送和接收数据的方法以及用于其的发送/接收装置。 用于发送数据的方法包括以下步骤:将对应于预编码矩阵的SLM序列子集的选择的映射算法(SLM)序列应用于相应的数据; 选择其中每个应用数据具有最小峰均功率比(PAPR)值的SLM序列; 以及发送所选择的SLM序列的索引和应用所选择的SLM序列的数据。 用于接收预编码矩阵的数据的方法包括以下步骤:接收从与预编码矩阵相对应的SLM序列子集中选择的SLM序列的索引,以及应用所选择的SLM序列的数据; 并使用由索引指示的SLM序列从应用SLM序列的数据中移除SLM序列,以便恢复数据。
