A Raised Cosine Filter is a type of filter commonly used in computer science that has an adjustable bandwidth controlled by the "roll off" factor. It is designed to shape the frequency spectrum of a signal to meet specific requirements, with a trade-off of requiring more frequency spectrum to...
Let's learn the equations and the filter model for simulating square root raised cosine (SRRC) pulse shaping.
1.The coherently coupled nonlinear Schr Ao¨G dinger equation is used to study the modulation instability of laser pulses propagating in fiber Bragg gratings withraised cosine apodizationfunction in both anomalous and normal dispersion regimes.利用相干耦合非线性薛定谔方程,研究了激光脉冲在升余弦变迹布拉格...
In anticipation of improved rising properties of the insertion loss and the return loss, the reflection and transmission coefficients of the cutoff filter are derived. These coefficients are obtained numerically by solving the Runge-Kutta method in which the differential equation valid for the ...
These coefficients are obtained numerically by solving the Runge-Kutta method in which the differential equation valid for the rectangular TE10 mode in a tapered waveguide satisfies the boundary conditions at the waveguide junctions. Next, the characteristics of the filter are analyzed by introducing a...

At the receiver, the matched filter 𝑔(𝑡)g(t) expressed in Equation (9) is used to maximize SNR. The filter output 𝑦(𝑡)y(t) is: 𝑦(𝑡)=𝑟(𝑡)∗𝑔(𝑡)=𝑠(𝑡)∗𝑝(𝑡)∗ℎ(𝑡)∗𝑔(𝑡)+𝑊(𝑡),y(t)=r(t)∗g(t)=s(t)∗p(t)...
