Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. High Peak-to-Average Power Ratio (PAPR), which leads to power inefficiency in the RF portion of the transmitter, is a major drawback of OFDM.

针对稀疏圆阵的波达方向估计问题，提出了解相干求根MUSIC算法（Sparse UCA Decorrelation Root-MUSIC，SDR）。通过改进传统的波束变换方法，进行相位校正，并在波束域进行误差补偿，得到具有共轭对称结构的波束域导向矢量。在波束域进行前后向平均处理和使用求根MUSIC算法(In order to solve the direction of arrival estimation of sparse circular arrays, a new understanding of the Sparse UCA Decorrelation Root-MUSIC (SDR) algorithm is proposed. By improving the traditional beam transform method, phase correction, and error compensation in the beam domain, a beam-domain steering vector with a conjugate symmetry structure is obtained. Averaging forward and backward in the beam domain and using the root-finding MUSIC algorithm)
