I am struggling understanding Spread Spectrum, namely Direct Sequence Spread Spectrum (DSSS)
After reading ALOT of material, things are still not clear for me.
This article did provide some help:
https://www.allaboutcircuits.com/te...anding-spread-spectrum-modulation-rf-systems/
But most books just say that the "Data" is multiplied in some manor by a "Spreading Code".
Is the "Data in" Normally a On-Off Keying Signal?
Is the spreading code always multiply the "Data" by either '1' or '-1' as the article above suggests?
How does the rate of the spreading code, effect the spreaded bandwidth?
And what actual hardware devices are used to accomplish such a task?
A mixer isn't going to 'invert' the signal... right?
Do I have to use some type of dual microwave transistor pair to accomplish this?
I have a lot of questions, and every book seems to gleam over these questions I find most important.
Can anyone with extensive knowledge on this shed some light on this?
Thank you!
