Thanks for the info, Caveat. Looks like I may have had run across one of your links
in all my searching

There are many question I have regarding SS, but one that's bothering me in
particular. Regarding the PN spreading sequence, these sequences obviously have to be
aligned perfectly in both transmitter and receiver. Naturally they could be kept in
sync if both circuits were initialized at the same time.

However, 3 things: 1) The circuits will not be initialized at the same time in 99% of
most cases, as in the use of, say, a portable field radio. 2) If they were
synchronized at the same time, well, no clock or oscillator is perfect. It would
eventually drift. 3) As I understand it, there is no initial "handshake" signal at
the beginning of transmission with the receiver to initialize/syncronize the PN
sequences on both ends.

So in short, how do the PN sequences became and remain synchronized through time?
Thanks.

Dave

Am looking to start experimenting with spread spectrum communications.

I'm pretty much starting from scratch in this area. Could anyone please
point me to a
good starting point? Thanks.
