摘要

我们考虑了一种通用的、带宽高效的无保护周期的多载波传输方案。通过使用具有良好时频局部化特性的非正交脉冲，即在时域和频域集中能量，可以限制码间和信道间的干扰。这让我们得到一个中等复杂度的接收器，使用迭代方法进行符号检测。通过计算机模拟评估了传输和检测方案的可实现性能，并与相应的无干扰传输的理论误差率进行了比较。

Iterative symbol detection for bandwidth efficient nonorthogonal multicarrier transmission

We consider a general, bandwidth efficient multicarrier transmission scheme without guard periods. Intersymbol and interchannel interferences are limited by using nonorthogonal pulses with good time-frequency localization characteristics, i.e., concentration of the energy in both time and frequency domains. This lets us derive a receiver of moderate complexity, employing iterative methods for the symbol detection. The achievable performance with the transmission and detection scheme is assessed by means of computer simulations and compared against the theoretical error rate of a corresponding interference-free transmission.
