>A highly underrated book is also Andreas Schwarzinger's "Digital Signal Processing in Modern Communication Systems", which covers how modems for these systems are actually implemented in real life and is quite approachable from an engineering standpoint.

The book is now in 2nd edition, and I've both of the 1st and 2nd editions, it's really a masterpiece.

The 2nd edition covers many of the 'gotchas' of OFDM implementation and covers several error detection and correction techniques, that're not in the 1st edition.
