What is PN code generator?

Description. 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.

How do I generate a PN code?

A linear-feedback shift register (LFSR), implemented as a simple shift register generator (SSRG), is used to generate PN sequences. This type of shift register is also known as a Fibonacci implementation. The Polynomial property determines the feedback connections of the shift register.

What is PN sequence spreading code?

A pseudo-noise code (PN code) or pseudo-random-noise code (PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences, Gold codes, Kasami codes, and Barker codes.

What are the generation and properties of PN sequence?

A PN data sequence is an M-sequence that is generated using a linear feedback shift-register circuit, as illustrated below. M is the number of shift registers. D(M) is the m^th shift register, and c₁,c₂,…,c_M are the coefficients of them.
