Alex was my advisor in grad school and I only know him to be honest, hard working and technically sound. I haven’t read this book closely but I’m not convinced that it’s poorly written based on cherry picking one paragraph from it.
Maybe someone else was sabotaging his work. Is it possible to cherry-pick one paragraph from it that is well-written and technically sound? Because I gave up after Chapter 1 and the beginning of Chapter 2. Maybe you could ask Alex what he thinks of how the book turned out and post his answer here?
I agree that it's mean, and I feel kind of bad about it, but I think the interests of the hundreds of people who are apparently interested in reading a book about software-defined radio outweigh the interests of the four authors to not have their feelings hurt. The problem is not that they've written this colossal pile of garbage; there's nothing wrong with that, and it's often the first step toward writing something worth reading. The problem is that that pile is being promoted (by Analog Devices, no less) as a useful way to learn about software-defined radio.
Not really. To geolocate a user the cell providers would need to know the absolute position of all the LTE repeaters and cells (which they might). But they'd also need to compensate for indoor propagation (which is much more complex than outdoor).
Also AGPS only provides satellite ephemeris, which enables a faster time to fix, not better accuracy.
A GPS repeater would only give accurate time, not position. The repeater only repeats the signal that's captured by the antenna on the roof. I use GPS repeaters frequently in my labs to supply timing to instruments.
