This paper presents a perturbative calculation of the power spectrum covariance matrix in the context of the large-scale galaxy redshift survey, including all relevant physical and observational effects. It estimates the matrix using the standard FKP estimator, providing a thorough and correct derivation of all the effects at the tree level in the trispectrum and updating some previously reported numerical factors.
