Reducing front-end bandwidth may improve digital GNSS receiver performance

A novel evaluation of filtering and quantisation losses for weak DS-CDMA receivers is presented. Using this method, joint optimisation of filter center frequency and bandwidth is conducted for one-, two- and three-bit quantisers. It is demonstrated that a joint lossanalysis of these effects is necessary to optimise front-end design.
