good explanations

Another technically in depth book from Springer. This recent addition to their portfolio explains the basis of the huge growth in mobile communications. Mostly in cellphones, but also in other devices like laptops that might communicate via a protocol like WiFi.

The basic idea is explained of using a pseudo-random approach to sharing the spectrum in a given volume of space. Very elegant! Torrieri shows how the military developed it during the long years of the Cold War. But, ironically, nowadays the civilian application market has overtaken the military sector in its usage.

The actual maths can get hairy. The book could actually go into much more of this detail. But the author decided to deprecate the more abstruse workings. Still, the book is certainly not a trivial read. It can be a solid but worthwhile challenge for a grad student to master its contents.
