“…Receiver local replica signals are often represented with relatively high resolution when compared with the received signal [9], [10]. It is thus assumed here that the quantisation effects of the local replica signal are negligible and so, for the sake of simplicity, the complex exponential and code replica of (8) are not quantised.…”

Traditionally, the effects of presampling filtering and of quantisation on the processing of GNSS signals have been dealt with in isolation. Analysis of the losses incurred during the quantisation process has almost invariably been based on the assumption that the signals at IF are distorted by additive white Gaussian noise. This paper, in contrast, considers the joint effect of filtering and quantisation, illustrates the need to consider these losses jointly and presents novel expressions for the total loss incurred.

“…The loss incurred by the filtering and quantisation of a signal can be evaluated by substituting (15) and (17) into (10). This, however, requires the evaluation of the signal mean, r s [n] and the noise autocorrelation function, R n [n], and these issues are the focus of this section.…”
