一种数字化基带成形实现新方法:基于码元间隔的定长滑动窗算法

A New DigitallyImplemented BaseBand Shaping Method:Algorithm of Fixed Length Sliding Window Based on Symbol Interval

针对数字化基带成形滤波的信号处理特点，提出二维分解截短基带波形的方法，进而形成基于码元间隔的定长滑动窗算法。该算法具有最小数据缓存量要求以及最小输出延迟的显著特点，是特别适合于数字化基带成形滤波的一种新实现方法，并可在序列间样点不等间隔的有限长序列与有限长序列、有限长序列与无限长序列之间的卷积运算上取得同样显著的实用效果。

This paper,aimed at the signal processing characterisitics of digitallyimplemented baseband shaping,puts forward a 2dimensiondecomposing method of shortened baseband waveform resulting in the introduction of the algorithm of fixed length sliding window based on symbol intervalThe algorithm is featured by its minimum requirement for data buffer and minimum output delay so that it is a practically useful method especially suitable for digitallyimplemented baseband shaping and can also achieve remarkable effects in its application on the convolution between finite length sequence and infinite length sequence and between two finite length sequences with sample intervals different from each other
