Full length Pseudo Random Noise (PRN) sequences are widely used in CDMA communication. The full length sequence number is not easily divisible. So it is not easy to generate a frequency of this value (equivalent to full length sequence) or multiple or sub-multiple thereof from a standard value of available crystal or frequency source.
Truncation of few bits from the full length may reduce this problem. Properties of Randomness of Truncated PRN have been studied and reported. The effect of truncation on the correlation properties has been studied in this paper exhaustively to address the applicability aspect of TPRN for CDMA applications.
