升余弦脉冲成形滤波器具有抗码间干扰（ISI）的特性，在数字通信中起着重要的作用。在执行匹配过滤后，无ISI属性保持不变。在这封信中，我们提出了一个新的家庭的脉冲整形滤波器。这些滤波器是ISI自由与或没有匹配滤波。使用这些新的脉冲成形滤波器，在调制解调器设计的解调中的计算负荷以及因此的硬件成本在某些应用中可能会降低。
The raised-cosine pulse-shaping filter plays an important role in digital communications due to its intersymbol interference (ISI)-free property. The ISI-free property holds after matched filtering is performed. In this letter, we propose a new family of pulse-shaping filters. These filters are ISI free with or without matched filtering. Using these new pulse-shaping filters, the computational load, and therefore the hardware cost in demodulation for modem design, might be reduced in some applications.
