![]() A feedback shift register, which is shown in figure 11.1, consists of consecutive stages of two state memory devices and feedback locig. The PN sequence is usually generated using sequential logic circuits. Although it is deterministic a pseudonoise sequence has many characteristics that are similar to those of random binary sequences, such as having a nearly equal number of 0s and 1s, very low correlation between shifted versions of the sequence, very low cross correlation between any two sequences, etc. Its autocorrelation also roughly resembles the autocorrelation of bandlimited white noise. ![]() Maximal-Length Sequence, PSEUDO-NOISE (PN) SEQUENCES, what is pseudo noise sequence ? pn sequence generator problems, advantages of pn sequenceĪ pseudo-noise (PN) or pseudorandom sequence is a binary sequence with an autocorrelation that resembles, over a period, the autocorrelation of a random binary sequence. ![]()
