  In this paper, we consider stationary measures of discrete-time three-state
quantum walks including the Fourier and Grover walks in the one-dimensional
lattice. We give non-uniform stationary measures by solving the corresponding
eigenvalue problem. Our new method is based on a reduced matrix, which is
different from the generating function approach in our previous work. As a
corollary, the Fourier walk on the cycle has a stationary measure with a
periodicity.
