【摘要】 卷积是一种重要的积分变换，它在信号处理领域有着非常重要的作用。基于线性正则正余弦变换，定义了两类新的线性正则正余弦变换的卷积运算，给出了线性正则正余弦变换卷积与已有卷积之间的关系，并推导出线性正则正余弦卷积定理。研究结果是经典傅里叶正余弦卷积理论在线性正则域内的进一步拓展。更多还原

【Abstract】 Convolution theorem is a basic property of linear canonical transform, which plays an important role in signal processing. In this paper, two new convolution operations of linear canonical sine and cosine transform are presented, and the relationship between the convolution of linear canonical sine and cosine transform and the existing convolution are definded. Thus we inferred the linear sine canonical transform convolution theorem and the weighted linear canonical cosine transform convolution theorem.更多还原
