Wow great you are persian, me too
and i think you can't work on any HOT topic if you live in iran do you know what i say ?
any how if you realy want to select a topic on wireless you can choose MIMO Because this topic may use in future of mobile telecommunication and it is great choice for next standard.
which university you are studying there ?
if you want book about 4G mobile telecommunication contact me haerifar@yahoo.com
maybe i can help you .

CDMA - OFDM with UWB also maybe use for 4G telecommuniaction and it is a hot topic , and you can choose it .
