Raised cosine
WebbRoot Raised Cosine (RRC) Filter The overall channel transfer function must be Raised Cosine (RC) as discussed above. One way of achieving it is to take square root of the … WebbThe reason it’s called the raised-cosine filter is because the frequency domain when is a half-cycle of a cosine wave, raised up to sit on the x-axis. The equation that defines the …

WebbRoot Raised Cosine Filter The root raised cosine filter produces a frequency response with unity gain at low frequencies and complete at higher frequencies. It is commonly used in communications systems in pairs, where the transmitter first applies a root raised cosine filter, and then the receiver then applies a matched filter. Webb19 okt. 2010 · So my solution for you is at first upsample of your NRZ data arbiary (4,8 or 16 , …) and then taking convolution of upsampled data and root raised cosine filter will have give simply the output that you need. and now it’s your ready signal to modulation. Matlab code : N = 10^4 ; % number of data up = 4; % upsampling data d = randsrc(1,N);

WebbThe Raised Cosine Pulse • The raised cosine pulse has attractive properties. It is not normally used for transmission itself, but it appears as part of receiver processing of the closely-related “square root raised cosine” pulse (see further below). The square root raised cosine is the most widely used pulse shape in communications.
