WebbLet us verify the length property of our root-raised-cosine filter: [5]: print("Filter length:", rrcf.length) Filter length: 129 Next, we will use this filter to pulse shape a sequence of QAM symbols. This requires upsampling of the sequence to the desired sampling rate. WebbThe raised-cosine filter is a filter frequently used for pulse-shaping in digital modulation due to its ability to minimise intersymbol interference. Its nam...
Root-raised-cosine filter - Wikipedia
Webb6 dec. 2004 · A 16 QAM digital signal at 10 Mbits/s filtered with a squared raised cosine filter with /spl alpha/=0, 25 is used as test signal. This analysis is addressed to show the key aspects on spectral regrowth due to phase margin and loop gain for Cartesian feedback, and time delay, phase and gain mismatch for feedforward.

Root Raised Cosine Filter (Custom IQ) - Keysight
http://www.fccdecastro.com.br/pdf/ShapingFilterDesign.pdf In signal processing, a root-raised-cosine filter (RRC), sometimes known as square-root-raised-cosine filter (SRRC), is frequently used as the transmit and receive filter in a digital communication system to perform matched filtering. This helps in minimizing intersymbol interference (ISI). The combined response of two such filters is that of the raised-cosine filter. It obtains its name from the fact that its frequency response, , is the square root of the frequency response of the raised-c… Webb升餘弦濾波器是一種經常用於數位調變的 脈衝整形 （ 英语 ： Pulse shaping ） 濾波器，它能夠最大限度地減少 符碼間干擾 （ 英语 ： Intersymbol interference ） （ISI）。 之所 … 1 反2 4-三甲基环戊烷
