基于连续干扰消除的超奈奎斯特信号迭代接收技术
SIC-based Iterative Reception Technique for Faster-than-Nyquist Signals
摘要
Abstract
In order to eliminate the interference introduced by faster-than-Nyquist( FTN) modulation tech-nique,a Turbo iterative equalization receiver based on successive interference cancellation ( SIC ) is de-signed. For single-carrier FTN system,the equivalent model of FTN signal is established firstly. And then according to the equivalent model and the soft information obtained from the decoder,the receiver recon-structs the interference and eliminates it with multiple SIC and decoding,and relatively low complexity is a-chieved. Likewise, the introduced interference is reconstructed and eliminated with many iterations in multi-carrier FTN system,according to the time-frequency characteristics of pulse filter and the soft infor-mation obtained from the decoder. Simulation shows that when the packing factor is not too small,receiver based on SIC-Turbo equalization can effectively eliminate the interference and acquire the bit error rate ( BER) performance approximate to the orthogonal transmission mode.关键词
