| Abstract | A DS-SSMA system model which applied windowing functions at the transmitter
and at the correlator receiver is presented. Two windowing schemes are considered in this
study -- the data bit windowing and the chip windowing. An analytical expression for the
signal-to-noise interference-ratio (SNR) is developed for both schemes to determine the
system performance using various windows. Effects on the correlation of pseudo-noise
(PN) sequences are investigated and numerical results are presented. It is shown that both
schemes result in an improved lower crosscorrelation values but an unsatisfactorily
reduced peak in the autocorrelation function. Based on these resulting characteristics, the
system performance is degraded with the use of windowing functions and that the
rectangular window, equivalent to no windowing applied, is still unequaled. |
