The Circuit Dictionary Basis Acquisition for the Compressive Sensing Wideband Receiver
研究压缩感知用于信号采样的工程化问题，给出了MWC（Modulated Wideband Converter）结构压缩感知宽带接收机的具体设计方案，提出了字典基自环测量获取方法和字典基的时延估计补偿算法，有效解决了工程化中因观测电路存在传输时延、通带波纹等与理论观测矩阵不一致，导致压缩感知处理数字调制信号时存在重构畸变的问题。实验测量了接收机的频率覆盖范围，验证了压缩感知的有效性，并以QPSK（Quadrature Phase Shift key…查看全部>>
The implementation of the compressive sensing was studied in this paper.Because of the transmission delay and the pass band ripple,the measurement matrix in a real compressive sensing receiver was different from that in theory. These differences caused the reconstruction error when digital modulated signals were compressively sensed.A self-loop measuring method of the circuit dictionary basis and an algorithm of time-delay compensation were proposed to solve…查看全部>>
