    摘要: A method for transmitting data in a multiple antenna system comprises the steps of: generating a transmission signal in plural antennas through the application of a precoding eight matrix to first and second antenna clusters including the plural antennas, and transmitting the transmission signal. The precoding weight matrix is a block diagonal matrix that is configured in a precoding weight corresponding to first and second antenna clusters respectively. The precoding weight of the first antenna cluster is selected according to a channel condition, and the precoding weight of the second antenna cluster is selected regardless of the channel condition but according to a rule.

    摘要: A method for detecting signals based on despreading and a signal transmitting method for the same are disclosed. Signals are spread according to the size of at least one spreading band, which is determined in consideration of a correlation degree of a frequency band in a communication system. A reception side which receives the signals detects the signals after despreading with respect to signals which are spread in a frequency band having a correlation degree equal to or greater than a predetermined level as a spreading band, among the reception signals. Thus, the dimension of the detected signals can be decreased.
