快速高效支撑集恢复算法

Rapid and Efficient Recovery Algorithm of Support Set

对调制宽带转换器(MWC)深入分析,引入子空间追踪(SP)算法中回溯思想,提出两种更为有效的恢复算法,称为随机多测量子空间追踪(RMSP)和减至单维子空间追踪(RSSP)算法,降低MWC系统中恢复模块的复杂度,使其更加具有实际作用。实验表明,即便在低信噪比(SNR)环境下,两种算法性能良好,并且证明能够快速且高效恢复支撑集。

Introduces the in-depth analysis of Modulated Wideband Converter （MWC）, and the idea of backtracking in Subspace Pursuit （SP） algo- rithm, proposes two more effective recovery algorithm, called Random Multiple Subspace Pursuit （RMSP） and Reduced Single Subspace Pursuit（RSSP） algorithm, which reduces the complexity of the recovery module and makes more practical in the MWC system. Experiments shows that even in the low Signal to Noise Ratio （SNR） environment, the proposed algorithm performs well and proves that can recover the support set quickly and efficiently.
