An approach for block transmission based precoding and equalisation with improved performance

Block transmission is very efficient method to combat with inter-symbol interference. However, the way it uses the guard intervals reduces spectral efficiency of the system. In this paper, we propose a new approach to block transmission based precoding and equalisation for frequency selective channels. Different with standard block transmission schemes, our method employs redundancy in a different way so that the channel energy can be better employed, thus leading to improved performance under the same code rate.
