dear all,
my graduation project is about power line communications i have some experiance in this field that i want to share it with every body and i wonder if any one has any information about power line modems that has high bit rate (Mega bps) they will mostly use ofdm please if you have any questions about the subject or have any info about my question replay this message
 

Try Maxim site:
h**p://www.maxim-ic.com/powerline.cfm
Data sheets on both ICs are available on request only but the started to offer evaluation kit ..
 

3years ago I tried to make a PLC telephone with TMS320VC5409 DSP, I used QAM and OFDM with 16 sub-carriers. the most problem I met is EMC.
