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 presente d 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 i n good agreement with the simulated ones, To suggest practical applications , experimental results are illustrated here for a cochannel 64-QAM radio re lay system.
