Abstract :
A new method is presented for channel equalization of EDGE (enhanced data rate for GSM and IS-136 evolution) cellular systems with 8-PSK modulation. It is shown that the 8-PSK EDGE equalization problem can be cast as an optimization problem, and an iterative optimization is proposed, which leads to near optimal performance with extreme computational efficiency. The new algorithm can easily be implemented into commercial signal processors
