  • A serial Turbo-DFH iterative demodulation and decoding scheme is proposed, with regarding the frequency transition as some code. In the scheme, the encoder consists of an outer encoder and an interweaver, serially concatenating with a transition function. At the decoder, a serial iterative structure is adopted to decode the codes. A novel soft-input and soft-output algorithm for DFH system is deduced. The simulated result shows that compared with the traditional DFH demodulation algorithm, the performance is improved obviously.
