Abstract

This paper examines the system level power reduction of wireless sensor nodes in medical applications by the use of source and channel coding. The reliability and energy savings of the serially concatenated Huffman and Reed-Solomon codes is presented, and the scheme with regards to medical applications is discussed. The results show that it is possible to have BER and compression gains in the system, but also show that computational time of purely software oriented implementations are not optimal.
