Hello Everyone,

I have a very basic question regarding BPSK modulation.

I am working on GNSS signals, and I came across BPSK(5) modulation scheme. But I don't know that what this "5" means?

As per my understanding, this only tells about the chipping rate of the modulating signal. which is 1.023Msps in BPSK(1), and here it is BPSK(5), so it means that the chipping rate would be 5*1.023Msps.

Can someone please make it clear for me that my understanding is correct OR is there something else that I am not getting?

Thank you
