Near-capacity turbo equalization using optimized turbo codes [PDF]
2007 Australasian Telecommunication Networks and Applications Conference, 2007 In this paper we analyze a turbo equalization scheme that combines maximum a posteriori probability (MAP) equalization and turbo decoding. Our aim is to optimize the turbo equalizer in order to approach the information capacity limit for channels with severe inter-symbol interference (ISI).
