The bandwidth of a raised cosine filter is most commonly defined as the width of the non-zero frequency-positive portion of its spectrum, i.e.: B W = R S 2 ( β + 1 ) , ( 0 < β < 1 )

What is raised cosine transmit filter?
Description. The Raised Cosine Transmit Filter block upsamples and filters the input signal using a normal raised cosine FIR filter or a square root raised cosine FIR filter. The block icon shows the impulse response of the filter.
What is raised cosine pulse shaping?
The raised cosine pulse is one type of Nyquist-II pulse. It possesses a transfer function given by. (3.67) where β is called the roll-off factor, which takes values between 0 to 1, and β/2T is called the excess bandwidth.
How ISI can be removed by employing a raised cosine filter?
Employ raised cosine filtering to reduce inter-symbol interference (ISI) that results from a nonlinear amplifier. Initialize a simulation variable for modulation order. Create square root raised cosine filter objects.
What is square root raised cosine?
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).
