Channel Equalization for Wireless Communications: From Concepts to Detailed Mathematics (IEEE Series on Digital & Mobile
In the past, channel equalization was addressed as a single chapter in a digital communications textbook for graduate students. The area has developed and increased so significantly that there is now a need for an entire textbook devoted to this subject. Filling this need for expanded coverage, Channel Equalization: From Concepts to Detailed Mathematics presents each channel equalization topic with incremental learning methodology, from the very fundamental concept to more advanced mathematical knowledge. Offering basic concepts to more complex modeling techniques, this textbook is suitable for both practicing wireless communication engineers and graduate students.
Why Read This Book
You will gain a single-source, mathematically rigorous yet accessible treatment of channel equalization that walks you from core intuition to full analytical detail. The book balances practical algorithm design (LMS/RLS, DFE, turbo and OFDM/MIMO equalization) with performance analysis, so you can both implement working systems and understand why they behave as they do.
Who Will Benefit
Graduate students and practicing wireless communication engineers who need a deep, application-oriented reference on equalization algorithms, performance analysis, and practical implementation techniques.
Level: Advanced — Prerequisites: Undergraduate signals and systems, probability & random processes, basic digital communications (modulation, sampling, baseband concepts), and linear algebra; familiarity with MATLAB or similar simulation tools is helpful.
Key Takeaways
- Explain fundamental channel models (AWGN, frequency-selective, multipath fading) and their implications for equalization design
- Design and analyze linear equalizers (ZF, MMSE) and decision-feedback equalizers with performance bounds

How It Compares
Covers equalization in far greater depth than the single-chapter treatment in Proakis' Digital Communications and complements Haykin's Adaptive Filter Theory by focusing more on application to wireless channels, OFDM, and MIMO.
