  Abstract

In next generation satellite broadcasting system and 5G based mobile communication, requirement of high throughput efficiency has been increasing continuously. FTN method which transmits signals faster the Nyquist rate is representative method for improving throughput efficiency sacrificed performance due to inter-symbol interference. However, performance degrade arising from Inter-symbol interference induced by increasing the interference rate. To overcome this problem, we propose the FTN method based on unequal error probability. Transmits the FTN interference differently applied to each group by priority algorithm. This method, by classifying group depending on the importance of the encoded bits of a channel encoder, improves performance in the same overall interference by allocating less FTN interference to the group to which important bits belong and more FTN interference to the group to which unimportant bits belong. The results of simulation show the performance of proposed method is better than that of conventional FTN method by about 0.2dB when the interference rates are 25% and 37.5%.
