description: The definition of FTN signal and the concept of FTN signal transmission are briefly presented, and the figure shows a comparison of waveforms between orthogonal transmission and FTN transmission. For a single carrier FTN transmission system, first introduce a model of a single carrier FTN transmission system, a method for modulating and demodulating a single carrier FTN signal, and an equivalent model of a single carrier FTN signal. To improve the bit error performance in a single carrier FTN transmission system, an FTN signal reception technology based on iterative equalization is being studied. An iterative receiver based on MMSE equalization can well remove the introduced interference with a few iterations, but there are many matrix multiplications and inverse operations. For this reason, an iterative reception scheme based on continuous interference cancellation has been developed at the receiving side. At the same time, the technology of receiving an FTN signal in a multipath channel is being studied, and an iterative scheme for receiving a Gaussian channel is applied to the multipath channel. By multiple successive interference cancellation and decoding, the error performance of the approximate orthogonal transmission can be achieved. to be received. For a multi-carrier FTN transmission system, the multi-carrier transmission system uses an orthogonal frequency division multiplexing (OFDM / OQAM) system with quadrature amplitude modulation. According to a method for quickly implementing an OFDM / OQAM system, modulation and demodulation of FTN multicarrier signals can be implemented based on the original orthogonal modulation of the transmit signal and demodulator without the need for mapping on the transmitting side and storing a large amount of data. On the receiving side, an iterative reception scheme based on continuous interference cancellation is still applied, and the detection of a multi-carrier FTN signal is completed by multiple iterative equalization. For multipath channels, subchannel fading rates are different due to channel frequency selectivity. Therefore, to implement multi-carrier FTN reception in multipath channels, the time-frequency response of the impulse filter is shaped according to the channel and OFDM / OQAM parameters. The part of the receiver with soft inverse display and continuous interference cancellation has been modified. Investigation of machine learning technology for demodulating FTN signals. Describes several methods: orthogonal frequency division multiplexing (OFDM) systems, multi-antenna systems, channel estimation and prediction systems, channel coding, modulation classification and DL (Deep Learning), focuses on DL work and uses the appropriate graph , to show.
