Digital Beamforming In Wireless Communications

Explosive growth of wireless communications is demanding increased system capacity for mobile communications satellites - and the expert authors of this first-of-a-kind book explore a promising, cost-effective solution: digital beamforming (DBF) technology.

In definitive detail, the authors explain why increasing the bandwidth of existing channels or allocating new frequency bands may not be feasible and why frequency reuse is becoming the most practical means for increasing system capacity. First they review the principles of DBF technology. Then they discuss beamforming techniques and results, state-of-the-art supportive technologies, and promising applications for wireless communications - complete with 165 figures, 300 equations, plus techniques and findings of researchers in related fields.

This book is an excellent tutorial or reference for understanding, designing, developing, and applying DBF systems in wireless communications. Communications engineers, technicians, managers, researchers, and graduate students alike will find solutions to four key problems:

Improving a wireless communications system's immunity to multipath fading
Reducing co-channel interference in a wireless communications system
Increasing system capacity of a wireless communications system
Achieving greater antenna array calibration accuracy
