The Burrows Wheeler Transform (BWT) is a block sorting algorithm which has been proven to be useful in compressing text data. More recently, schemes based on the BWT have been proposed for lossless data compression of sources with memory using LDPC codes. In this paper we design a source controlled turbo coding scheme for the transmission of sources with memory over AWGN channels based also on the Burrows Wheeler Transform. Our approach integrates the BWT with a turbo code and employs different energy allocation techniques for the coded symbols before their transmission. Simulation results show that the performance of the designed schemes are close to the Shannon theoretical limit.
