Abstract :
Presents the performance evaluation of the matched filter with reference filtering detector for both the additive white Gaussian noise channel and the non-frequency-selective Rayleigh fading channel. This detection scheme utilises a reference filter to estimate the noise variance at the output of the detecting matched filter. A definitive relation between the performance of the acquisition scheme and the ratio of Doppler frequency to chip rate is also derived. The results obtained show the relationship between the system performance and design parameters such as received signal to noise ratio, full or partial code correlation and threshold values
