PRQS Sequences Characteristics Analysis by Auto-correlation Function and Statistical Properties
The goal of this paper is to describe the generation and present
characteristics sequences analysis called pseudo random
quaternary sequences witch show very remarkable properties. To
emulate a real traffic data transmission using Differential Phase
Shift keying (DQPSK) modulation format with four levels of
phase, we are affecting towards pseudo random quaternary
sequences. In particular, we will focus on the autocorrelation
function study and statistical properties. Two PRQS Analysis
respectively for a length of 63 symbols (m=3) and a sequence of
16383 symbols (m=7) have been used to confirm its properties.
We will show an importance of the sequence length. The
simulations results are then presented and discussed.
