Pulse-shape filtering in communications systems choices for a matched filter is the root raised cosine filter described filtering in communications systems. Square-root raised cosine signals a practical way of reducing the side-lobes of the spectrum of the navigation signals could be to use a raised cosine filter. Raised-cosine filters are commonly used in digital data communication systems to limit intersymbol interference (isi) the impulse response of a raised-cosine filter is zero at each adjacent.
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.
