Tutorial on Channel Equalization for Mobile

Channels.Equalizer design for multi-path channels is closely

linked to the distribution of zeros of mobile channels. While in

a deterministic scenario, equalizers can be designed based on

knowledge of the exact locations of zeros in the complex plane,

mobile channels like in GSM/EDGE systems ask for a different

approach.We summarize some of

the results obtained in [Schober01] on the importance of the

distribution of zeros of the channel and finally explain some

equalization respectively prefiltering strategies to overcome the

burden of inter-symbol interference.
