摘要
Systems and methods are disclosed that attempt to increase spectral efficiency by using Faster-than-Nyquist (FTN) transmission. In one embodiment, a method at a transmitter includes partitioning bits into K bit streams, obtaining K power scaled symbol streams, combining the K power scaled symbol streams to obtain a stream of transmission symbols, and transmitting the stream of transmission symbols using FTN signaling. At the receiver, the received symbols are partitioned into K symbol streams, and demodulation and decoding is performed by: (i) demodulating and decoding the Kth symbol stream of the K symbol streams to obtain a Kth set of bits; (ii) mapping the Kth set of bits to a Kth set of symbols; and (iii) for each one of k=K−1, . . . , 1: demodulating and decoding a kth symbol stream of the K symbol streams to obtain a kth set of bits. The demodulating and decoding includes performing interference cancellation.
