Communication Systems worldwide have provided a rapidly growing and useful range of services and are
continuing to evolve using a multitude of Signal Processing techniques. The 4th International Conference on
Signal Processing and Communication Systems, ICSPCS’2010, follows the very successful ICSPCS'2009. A major
objective of the Conference will be to pursue the progression from communication and information theory through
to the implementation, evaluation and performance improvement of practical communication systems using Signal
Processing technology. The Conference incorporates the 12th International Symposium on DSP and
Communication Systems, DSPCS’2010, and the 9th Workshop on the Internet, Telecommunications and Signal
Processing, WITSP'2010, and as such is also planned to be a forum for presenting research into topics ranging
from those of the physical layer to the application layer. All aspects of the protocols and processes required for
the future Internet to operate better and the applications to utilize the full potential offered by the current and the
emerging networking infrastructure are also encompassed. In addition, we expect that, as during the previous
events, there will be several papers dealing with image, video and audio processing for multimedia, medical and
forensic applications, as well as with the security of private and corporate data.
