Sammanfattning
In order to increase the spectral efficiency of single-carrier communications, alternative wave forms obtained by faster than Nyquist (FTN) signaling can be used. FTN was pioneered in the mid-70s by Mazo with his milestone publication. FTN signaling increases the number of symbols transmitted within the same time interval which means implementing it can reach a higher data rate and improve the spectral efficiency. This raises the ISI problem, which is well known in multi-path environments, but a technique called equalization can compensate this problem. The aim of this project is to investigate spatially coupled LDPC coded FTN signaling, using the results without coupling as a reference. In particular, coupled and uncoupled schemes with binary and 16-QAM modulation (or higher order if time is available) will be investigated to understand the impact of spatial coupling on the trade-off between modulation order and FTN parameters. Spatial coupling will be applied at the code level or between the code and the channel. The impact of spatial coupling on FTN signaling will be investigated by evaluating the performance with different parameters and comparing with results for uncoupled systems from the literature.
