Understanding Antennas based on GPS

[ahmadicabara]

hi,

I know that a GPS receiver module receives a number of signals coming from GPS satellites and the receiver can distinguish between them based on a number 1-32. Is there a limit to the number of signal one can send on a specific carrier frequency? Is there a limit to the number of signals a receiver can decode at any point in time and if yes what is the component that is responsible for this number?



Note: I hope I posted in the right forum :D

Regards,

Hi there,
welcome to the forums :)

there 's lots of good info on the www about GPS signal decoding,
here's just one of the many GOOGLE returned
http://wireless.ictp.trieste.it/school_2003/lectures/carlo/GPS/DECODING.HTM

There are many ways to encode signals, regardless of if they are from a GPS satellite or multiple telephone signals through a optical fibre or microwave link etc
to name a few...
TDM = Time Division Multiplexing
FDM = Frequency Division Multiplexing
CDMA = Code Division Multiple Access

Some google searching on digital signal multiplexing systems is likely to bring up lots more examples :)

cheers
