  A recent type of B-spline functions, namely trigonometric cubic B-splines,
are adapted to the collocation method for the numerical solutions of the
Kuramoto-Sivashinsky equation. Having only first and second order derivatives
of the trigonometric cubic B-splines at the nodes forces us to convert the
Kuramoto-Sivashinsky equation to a coupled system of equations by reducing the
order of the higher order terms. Crank-Nicolson method is applied for the time
integration of the space discretized system resulted by trigonometric cubic
B-spline approach. Some initial boundary value problems are solved to show the
validity of the proposed method.
