| Summary: | We have described in previous work the generation
of PN-sequence by employing a 4-bit shifted Linear Feedback
Shift Register (LFSR) for application into Direct Sequence
Spread Spectrum (DSSS) system by simulation. In this paper,
is proposed a pseudo random number generator (PRNG)
circuit consisting of 24-bit shift registers (LFSR) which has
much longer period to improve statistical properties. We
simulated the LFSR circuit by using Multisim 11.0 and the
pseudo random sequence generated is tested with statistical
test of NIST Test suite. The sequence is passed the entire
selected test and we concluded that our pseudo random
sequence has long enough period to be considered as random.
