Combined block-turbo coding and RBF-based equalization with decision feedback

The combination of the radial basis function (RBF) based-equalizer with decision feedback and block turbo decoder is studied. In block turbo coding (BTC) which is based on iterative decoding of a product code, the RBF-based equalizer enters the iteration loop. There is some improvement in performance of this new scheme compared with the case that they are used individually, and also the system of the decision feedback equalizer and block turbo decoder.
