Direct sequence spread spectrum (DSSS) is a trying to cut technology that has only been around for three to four decades. Anti-jamming, multiple input multiple output, and low likelihood of intercept (LPI) properties of DSSS, as well as its simplicity of deployment, make it a suitable transmitting system for both military and commercial applications. In the majority of current remote-control units (RCUs) which manage tiny UAVs or helicopters, DSSS is a conventional way for providing command and control data. The DSSS alone would not be adequate to support numerous accesses when the quantity of users or planes to regulate grows. To give an efficient multiple access, a hybrid approach should be used, which requires combining other multiple access strategy, including such time division multiple accesses (TDMA), with DSSS to provide an efficient multiple access. Frequency Division Multiple Access (FDMA) and other multiple access methods may also be used. However, additional resources are needed, such as bandwidth and broadband RF front ends. As a consequence, TDMA with DSSS is an option worth considering. The hybrid variant uses DSSS's broadband feature to enable data transfer without collisions. This study provides a detailed frame structure to execute the IEEE 802.11b standards DSSS to combine this with TDMA, and then tests the BER performance of the final architecture. In MATLAB, BER data is simulated for different code spreading factors.
