If I understand your question correct spreading gain it's when you have system suppose you have LNA and PA and the total gain it's about lats say 60dB, spreading gain as I understand anyway where and how much gain you are define in LNA and PA (total 60dB), this where important in receivers for example you not put all the gain in the same chain you are separting to avoid Oscillation!!!!
Hopping that I successed to understand and to explain.
Good guess, but I think not. The spreading gain is most likely a matched filter gain that you get when you spread a modulated signal out over a bigger bandwidth than needed. I think the proper term is "coding gain". For instance, if you have a 1 MHz modulation, by by spread spectrum techniques you spread it out over a 100 MHz RF bandwidth, then it will reject noise and interferring signals by many additional dB's after it is demodulated.
