摘要

我们提出了反馈控制的多输入多输出码分多址(FC-CDMA)技术。该系统在接收机的有限持续脉冲响应(FIR)滤波器中产生空时频(STF)码。该系统获得了路径分集增益、频率分集增益和空间分集增益，提高了信噪比。结果表明，该系统在多径信道上显著提高了异步MIMO多址性能。

Heuristic approach to construct three-dimensional codes for feedback-based MIMO-CDMA

We propose feedback-controlled code-division multiple access (FC-CDMA) using the multi-input multi-output (MIMO) technique. The proposed system generates a space-time-frequency (STF) code at the finite-duration impulse response (FIR) filter in the receiver. The proposed system obtains path diversity gain, frequency diversity gain, and space diversity gain, and increases the signal-to-interference plus noise ratio (SINR). It is shown that the proposed system provides us with a significant improvement in asynchronous MIMO multiple access performance over multipath channels.
