摘要

除了提供确定性的多用户干扰(MUI)消除和低复杂度收发器外，还提出了一种互正交用户码-接收机(AMOUR)系统，以保证传输符号的可识别性，而不受信道null的影响。为了使AMOUR具有更大的灵活性，本文开发了一种Vandermonde-Lagrange AMOUR系统，该系统实现了相同的MUI消除特性，并在代码分配过程中提供了额外的优势。我们还在VL-AMOUR框架内推导了盲自适应均衡器，并通过仿真说明，它们的性能非常接近具有完美信道信息的理论边界。

Vandermonde-Lagrange mutually orthogonal flexible transceivers for blind CDMA in unknown multipath

A mutually-orthogonal usercode-receiver (AMOUR) system was previously proposed to guarantee identifiability of transmitted symbols irrespective of channel nulls in addition to offering deterministic multiuser interference (MUI) elimination and low complexity transceivers. Motivated by the desire to equip the AMOUR with added flexibility, we develop in this paper a Vandermonde-Lagrange AMOUR system that achieves the same MUI eliminating property and offers additional advantages in the code assignment procedure. We also derive blind adaptive equalizers within the VL-AMOUR framework and illustrate via simulations that they perform very close to the theoretical bound derived with perfect channel information.
