WebbPN Sequences or Pseudo Noise Sequences are an integral part of existing mobile cellular systems. A PN sequence consist of ones and zeros which are determined by precise mathematical rules. There are three well-known PN Sequence families: 1.m-Sequence. 2. Gold Sequence. 3. Kasami Sequence.

Webb20 dec. 2006 · The data input to the LFSR is generated by XOR-ing or XNOR-ing the tap bits; the remaining bits function as a standard shift register. The sequence of values generated by an LFSR is determined by its feedback function (XOR versus XNOR) and tap selection. For example, consider two 3-bit XOR based LFSRs with different tap …

The PN Sequence Generator block generates a sequence of pseudorandom binary numbers using a linear-feedback shift register (LFSR). This block implements LFSR using a simple shift register generator (SSRG, or Fibonacci) configuration.
