Simulasi Direct Sequence Spread Spectrum (DSSS) Pada Modulasi Binary Phase Shift Keying (BPSK) [PDF]
Spektral, 2021 Spread spectrum is a data transmission technique that spreads out information spectrum energy signals in a frequency band that is much larger than the minimal spectrum. One of the spread spectrum techniques is Direct Sequence Spread Spectrum (DSSS).

Jurnal SPEKTRUM, 2021 The communication channel cannot be separated from noise, interference and fading.To minimize mutual interference, you can use a scatter code. This research uses Gold Codewith a code length of 31. This simulation aims to determine the effect of the number of multipathcomponents on the Gold Code performance of multipath fading channels.

Interference management using direct sequence spread spectrum (DSSS) technique in LTE-Wi-Fi network
Journal of Fundamental and Applied Sciences, 2018 In this paper, an enhance DSSS technique was proposed which considers both serving and its neighbouring base stations in the network. New coefficients, chip rate coefficient (a) and radius fraction coefficient (b) were applied in DSSS technique in order to improve the SINR value. First, SINR MUE and SINR WUE for the standard DSSS were simulated.
