# rcosdesign

Raised cosine FIR pulse-shaping filter design

## Description

returns the coefficients `b`

= rcosdesign(`beta`

,`span`

,`sps`

)`b`

that
correspond to a square-root raised cosine FIR filter with
rolloff factor specified by `beta`

. The
filter is truncated to `span`

symbols,
and each symbol period contains `sps`

samples. The order of the filter,
`sps*span`

, must be even. The
filter energy is 1.

## Tips

If you have a license for Communications Toolbox™ software, you can perform multirate raised cosine filtering with streaming behavior. To do so, use the System object™ filters,

`comm.RaisedCosineTransmitFilter`

and`comm.RaisedCosineReceiveFilter`

.
