A simplified analog group delay equalizer and its performance for point-to-point cochannel radio relay system applications

The implementation of a simplified analog group delay equalizer is presented for a high‐capacity SDH radio relay system. It provides good performance in terms of simple hardware and easy tuning, and the measured results are in good agreement with the simulated ones. To suggest practical applications, experimental results are illustrated here for a cochannel 64‐QAM radio relay system. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 397–400, 2001.
