摘要： Disclosed is an apparatus and a method for controlling automatic gain in a wireless communication system using a Time Division Duplex (TDD) scheme. The apparatus comprises a power detecting unit for detecting a power of a TDD frame signal on a receive path; an Automatic Gain Control (AGC) synchronizing signal generating unit for generating an AGC synchronizing signal enabled or disabled either during a Down Link (DL) frame or during an Up Link (UL) frame of a TDD frame; an automatic gain calculating unit for calculating a gain control value based on the power detected by the power detecting unit either during the DL frame or during the UL frame of the TDD frame in response to the AGC synchronizing signal; and an AGC unit for performing gain control for the TDD frame signal on the receive path on the basis of the calculated gain control value. Hence, as AGC is performed during only an actual receive frame, the optimized demodulation performance can be maintained.

摘要： A method for generating, operating, and using a sparse w-NAF key for encryption is disclosed. The method for generating a key comprises generating a string of a number of coefficients, in which at most one coefficient, excluding 0, among a consecutive w number of coefficients, corresponds to a positive odd integer equal to or less than 2w (w being a natural number equal to or more than 2); and outputting the generated string as a key. Accordingly, an encryption is executed through an exponential operation or scalar multiplication using a sparse w-NAF key having the scarce coefficients, excluding 0, such that an encryption pace is improved.
摘要翻译：公开了一种用于生成，操作和使用用于加密的稀疏w-NAF密钥的方法。用于产生密钥的方法包括生成一系列系数，其中连续的w个系数中除了0以外的至多一个系数对应于等于或小于2w的正奇整数（w为自然数等于或大于2）; 并输出生成的字符串作为关键字。因此，通过使用具有稀疏系数的稀疏w-NAF密钥通过指数运算或标量乘法来执行加密，排除0，使得加密步速提高。
