Energy levels, radiative transition probabilities, and autoionization rates for [Ne]$3s^{2}3p^{6}3d^{9}4l^{\prime }nl$, [Ne]$3s^{2}3p^{5}3d^{10}4l^{\prime }nl$ ($n=4$–6), and [Ne]$3s^{2}3p^{6}3d^{9}5l^{\prime }nl$ ($n=5$–7) states in Cu-like tungsten (W${}^{45+}$) are calculated using the relativistic many-body perturbation theory method (rmbpt code), the multiconfiguration relativistic Hebrew University Lawrence Livermore Atomic Code (hullac), and the Hartree-Fock relativistic method (cowan code). Autoionizing levels above the [Ne]$3s^{2}3p^{6}3d^{10}$ threshold are considered. It is found that configuration mixing among [Ne]$3s^{2}3p^{6}3d^{9}4l^{\prime }nl$ and [Ne]$3s^{2}3p^{5}3d^{10}4l^{\prime }nl$ plays an important role for all atomic characteristics. Branching ratios relative to the first threshold and intensity factors are calculated for satellite lines, and dielectronic recombination (DR) rate coefficients are determined for the singly excited [Ne]$3s^{2}3p^{6}3d^{10}nl$ ($n=5$–7) as well as doubly excited, nonautoionizing [Ne]$3s^{2}3p^{6}3d^{9}4s4l$ ($l=s,p,d,f$), [Ne]$3s^{2}3p^{6}3d^{9}4p4l$ ($l=p,d,f$), [Ne]$3s^{2}3p^{6}3d^{9}4d^2$, [Ne]$3s^{2}3p^{5}3d^{10}4s4l$ ($l=s,p,d$), and [Ne]$3s^{2}3p^{5}3d^{10}4p^2$ states in Cu-like W${}^{45+}$ ions. Contributions from the autoionizing doubly excited [Ne]$3s^{2}3p^{6}3d^{9}4l^{\prime }nl$, [Ne]$3s^{2}3p^{5}3d^{10}4l^{\prime }nl$, and [Ne]$3s^{2}3p^{6}3d^{9}5l^{\prime }nl$ states (with $n$ up to 500), which are particulary important for calculating total DR rates, are estimated. Synthetic dielectronic satellite spectra from Cu-like W are simulated in a broad spectral range from 3 to 70 Å. These calculations provide highly accurate values for a number of W${}^{45+}$ properties useful for a variety of applications, including fusion applications.
