Answer / siva subrahmanyam

PN sequence code means Psuedo Noise code.. this term is
usually used in the communication, while transmitting info
from one place to other using digital techniques..

Actually it doesn't convey any info regarding the message
signal and its purpose is for noise reduction. this is
first generated by a PN sequence generator and is added to
the actual signal as redundant info. At the rx side by
keeeping xcertain threshold value we will remove it so that
noise effect to the signal is relatively less.

Answer / mahendra patil.

PN Sequence is a very
high frequency signal
which appears similar
to noise hence also
called pseudo noise
