We present estimates of cosmological parameters from the application of theKarhunen-Loeve transform to the analysis of the 3D power spectrum of densityfluctuations using Sloan Digital Sky Survey galaxy redshifts. We use Omega_m*hand f_b = Omega_b/Omega_m to describe the shape of the power spectrum, sigma8for the (linearly extrapolated) normalization, and beta to parametrize lineartheory redshift space distortions. On scales k < 0.16 h/Mpc, our maximumlikelihood values are Omega_m*h = 0.264 +/-0.043, f_b = 0.286 +/- 0.065, sigma8= 0.966 +/- 0.048, and beta = 0.45 +/- 0.12. When we take a prior on Omega_bfrom WMAP, we find Omega_m*h = 0.207 +/- 0.030, which is in excellent agreementwith WMAP and 2dF. This indicates that we have reasonably measured the grossshape of the power spectrum but we have difficulty breaking the degeneracybetween Omega_m*h and f_b because the baryon oscillations are not resolved inthe current spectroscopic survey window function.Comment: LaTeX, 8 pages, 3 figures; figures updated, references added, minor  changes to text; accepted by Ap
