What is a PN sequence?
The PN Sequence Generator block generates a sequence of pseudorandom binary numbers using a linear-feedback shift register (LFSR). Pseudonoise sequences are typically used for pseudorandom scrambling, and in direct-sequence spread-spectrum systems. For more information, see More About.
How do you find the period of a PN sequence?
Explanation: The PN sequence length is N = 2m – 1 = 16 – 1 = 15. 2. A pseudo-noise (PN) sequence is generated using a feedback shift register of length m = 4. The chip rate is 107 chips per second.
Is PN sequence used in CDMA?
PN Sequence
The DS-CDMA system uses two types of spreading sequences, i.e., PN sequences and orthogonal codes. As mentioned above, the PN sequenc is generated by the pseudo-random noise generator. It is simply a binary linear feedback shift register, consisting of XOR gates and a shift register.
What is run length property of PN sequences?
The length of a run is the number of digits contained in a given run. In PN sequences about half of the runs are of length 1, about a quarter of the runs are of length 2, about an eighth of the runs are of length three and so on.
