摘要

提出了一种新型的非正交频距脉冲型多载波信号(脉冲型频谱高效频分复用，PS-SEFDM)。这样的信号引入了带外发射(OOBE)和占用带宽控制。提出了基于IFFT/FFT和迭代BCJR算法(Bahl, Cocke, Jelinek和Raviv)解调器的PS-SEFDM生成和接收方案。这种信号的传输性能与SEFDM和OFDM相当，但通过使用最佳脉冲形状可以大大降低OOBE电平。

Pulse-Shaped Multicarrier Signals with Nonorthogonal Frequency Spacing

A new type of pulse-shaped multicarrier signals with nonorthogonal frequency spacing (pulse-shaped spectrally efficient frequency division multiplexing, PS-SEFDM) is proposed. Such signals introduce both out-of-band emission (OOBE) and occupied bandwidth control. The PS-SEFDM generation and reception schemes based on IFFT/FFT and iterative BCJR algorithm (Bahl, Cocke, Jelinek and Raviv) demodulator are proposed. The BER-performance of such signals is of comparable level with SEFDM and OFDM, but OOBE level can be greatly reduced by using optimal pulse-shapes.
