The following article provides a description of an application of the pseudo random signals generators, based on dynamic linear feedback shift registers, used in the DSSS spread spectrum communication. Due the changes of generator's feedback loop in time, the length of pseudo random sequence is much longer. An implementation of the dynamic linear feedback shift register generator (DLFSR) in VHDL language was created. Exemplary communication chain with FPGA was designed and constructed. Some signals measurements were done. Based on carried out measurements some conclusions about the use of the DLFSR generators were drawn.
