To measure noise performance of various correlation techniques, a generic theoretical code variance expression is provided here for arbitrary signal spectra and additive white Gaussian noise. The expression is valid for code discriminators using noncoherent dot-product type structures whose coherent component is based on linear reference waveform shaping. The variance of the proposed BOC-gated-PRN (BOC-GPRN) discriminator and other existing "strobe correlators" are analysed theoretically and validated empirically. Parameter selections are suggested for their optimum noise performance.
