Study on potentiality of truncated PRN sequences for communication

Truncation of few bits from the full length Pseudo Random Noise (PRN) sequence causes the appearance of a truncation noise in their autocorrelation deteriorating considerably the system performance. Sometimes, there is the need to shorten the PRN-sequence to decrease the acquisition time and to match the data field size in frame structures. Some properties of truncated PRN sequences have been studied in this paper particularly keeping in mind its application in communication system. 9 stage shift register has been considered as a case study in this paper.
