In reply to Phil Neumiller. Thanks for the feedback. I just found out the reason for the bug. The code is updated in the recent revisions of the book but the update was not picked up in the code package. I have sent you the updated files that include the fix. Thank you for your valuable feedback. I spent some time reviewing the code package and made sure the updates are picked up in the downloads.

When the raisedCosineFunction is called from constellation_plot it evaluates to 0 so the assignment of p(0) to 1 fails. Thanks, Phil Neumiller

All the topics well covered with theoretically. The topics are explained in a concise and sufficient and their details are included. Simulations are really good and understandable written. It’s good way to learn digital modulations and improve background theoretically with simulations.

Thanks Mathuranathan!

If you bought the physical copies of the books, is there a way that you can get the ebook or do you have to buy it separately?

In reply to Cyro. Yes, it has basic matlab script to estimate and compensate IQ impairments for the single-branch IQ impairment model. Previous section also has matlab script to to create IQ imbalance impairment in a complex baseband. The entire book has examples on each topics described. All script written from scratch, no in-built functions from communication toolbox is used in the scripts. So you can understand each and every detail that will help in building your own programs. Thank you.

Pls does the topic 6.4.1 Blind estimation and compensation offers a basic Matlab script for I/Q impairment and blind (circularity-based) compensation ?
Thanks

In reply to Lucas Saraiva. It is a basic simulation involving modulator, channel and receiver using waveform simulation technique. It does not cover other details.

Does the topic 2.2.3 “End-to-end simulation” of BPSK deal with timing synchronization?
and what about the phase and frequency?
