Method for assigning code and producing code-pair by selecting LS code

摘要

The present invention is CDMA (Code Division Multiple Access) method in mobile communication in using orthogonal spread about as, especially LS (Large Synchronization) code selection in accordance with code pairs generated peak power to average power ratio (PAPR: Peak-to- reducing the Average Power Ratio), by assigning a code LS with successive interference cancellation window (IFW: relates to a pair of code generation and code allocation method according to the LS code selection to increase the length of interference Free window). ; According to the present invention 180 between the code assigned to the I and Q components is also to propose a sign pairs of the phase shift to the minimum to improve the peak power to average power ratio, and the code assignment method the length provisionally interference cancellation window to improve the It has the effect that increased.; Code assignment, interference cancellation window, the peak power to average power ratio
