Update: Correction in Matlab code for raised cosine filter

by Krishna Sankar on May 25, 2008

Thanks to the keen observation by Mr. Phan Minh Hoang, I was notified that the Matlab/Octave scripts provided along with the topic raised cosine filtering was not behaving properly. Reason: I was not taking care [...]

Eye diagram with raised cosine filtering

by Krishna Sankar on May 1, 2008

Eye diagram following raised cosine filtering with alpha=0.5

We have discussed about probable transmit pulse shaping filter and have observed that raised cosine filtering filtering allows a simpler implementation, albeit at the cost of increased bandwidth. Let us know understand the eye diagram, [...]

Raised cosine filter for transmit pulse shaping

by Krishna Sankar on April 22, 2008

Time domain response of raised cosine filter

In the previous post on transmit filtering using Nyquist pulse, we had briefly learned that the information symbol with a symbol period can be transmitted without inter symbol interference (ISI) by using Nyquist pulse, . [...]
