$$w_0^{cc} = w_n^{cc} = \frac{1}{n^2 - 1 + \mod(n,2)}$$

$$w_k^{cc} = \frac{c_k}{n} \left(1 - \sum_{j=1}^{[n/2]} \frac{b_j}{4j^2 - 1} \cos(2j \theta_k) \right ), \ k=0,1,\ldots,n$$

$$b_j = \begin{cases} 1, \ j=n/2 \\ 2 , \ j < n/2 \end{cases} , \quad c_k = \begin{cases} k = 0 \mod n \\ 2 \ {\rm otherwise} \end{cases}$$
