I have some knowhow on noise cancellation in the receiver of radar or other communication system. But I don't know how to implement using FPGA for better result.
Now aday some projects have been performed on this area.but I am not clear about the future scope and how I can improve the scopes stated. If an MTech project proposal has been posted in IEEE, I realy seek to know. ....etc

ABSTRACT
Wireless phones are increasingly being regarded as essential communications tools, dramatically impacting how people approach day-to-day personal and business communications. As new network infrastructures are implemented and competition between wireless carriers increases, digital wireless subscribers are becoming ever more critical of the service and voice quality they receive from network providers. A key technology to provide near-wireline voice quality across a wireless carrier's network is echo cancellation.

Abstract
Frequency offsets or frequency spreads distort theorthogonality between sub-carriers, which results in inter-carrierinterference (ICI), in regular OFDM communication systems. Inorder to combat the impact of ICI on OFDM systems, an ICImitigation technique by jointing symbol shift cancellation (SSC)and adjacent sub-channel interference filter (ASIF) is proposedin this paper. At first, the symbol shift cancellation (SSC) methodis used to cancel the impact of ICI on the far sub-carriers, andthen the adjacent sub-channel interferen ....etc

ABSTRACT
The term echo cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network.



Two sources of echo have primary relevance in telephony:
acoustic echo and
hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appe ....etc
