Improved synchronization performance in DSSS systems

, 2002
This paper deals with the synchronization properties of a family of spreading codes, called concatenated codes. New synchronization algorithms are introduced, and the performance of these algorithms is discussed both analytically and by simulation. It turns out that with a minimum of extra hardware, the mean phase acquisition time can be considerably ...
