摘要： A method for timing synchronization of an OFDM signal is useful for a sniffing base station (BS) to establish BS synchronization with another BS in a mobile communication system. The method comprises estimating a timing offset of the signal from a reference sampling instant. In estimating the timing offset, first determine a maximum detection range of an estimable timing offset estimated solely by an observed phase difference between two pre-selected pilot symbols in the signal. Then the timing offset is determined as an integer multiple of the maximum detection range plus a residual timing offset. The multiplying integer is determined from a set of candidate integers. According to a candidate integer under consideration, a portion of an OFDM-signal sample sequence is masked out and a resultant signal to interference plus noise ratio (SINR) is computed. The multiplying integer is determined by identifying the candidate integer having the greatest SINR.
摘要翻译：用于OFDM信号的定时同步的方法对于嗅探基站（BS）在移动通信系统中与另一BS建立BS同步是有用的。该方法包括估计来自参考采样时刻的信号的定时偏移。在估计定时偏移时，首先确定仅由信号中的两个预先选择的导频符号之间的观测相位差估计的可估计定时偏移的最大检测范围。然后，定时偏移被确定为最大检测范围加上剩余定时偏移的整数倍。乘法整数是从一组候选整数中确定的。根据所考虑的候选整数，将OFDM信号采样序列的一部分屏蔽掉并计算出结果的信号与干扰加噪声比（SINR）。通过识别具有最大SINR的候选整数来确定乘法整数。

摘要： Disclosed herein is a method of implementing Orbital Angular Momentum (OAM) for radio communications in general and LTE in particular. Common prior art so far recreate said vorticity (axial rotation of the Poynting vector) by using ring-shaped antenna arrays. This application proposes to create said vorticity in signal processing without the need of any space diversity (ie work with a single antenna). In the present application, the main idea is to apply an Hilbert transform in frequency domain to the Fourier transform of the analytical representation of a band-limited OFDM signal. Said Hilbert transform is then approximated by a development in series into orthogonal twisted modes. This can be seen as an inverse Fourier transform of the complex analytical signal. Therefore an OAM IFFT based transmitter is proposed where parallel IFFTs are performed for each OAM mode and superimposed.
