摘要:
本工作考虑使基于正交线性调频分复用(OCDM)的系统实现最大多径分集的问题。我们定义并研究了一种仿射OCDM(A-OCDM)系统,其中通过调整线性调频参数来实现频率选择性信道所提供的最大分集。与线性星座预编码OCDM相比,所提出的系统还通过消除预编码需求降低了实现复杂度。文中提供了验证性仿真,表明A-OCDM还保持了OCDM系统对扩频所引入干扰的鲁棒性。
英文摘要:
This work considers the problem of enabling maximum multipath diversity of orthogonal chirp division multiplexing (OCDM)-based systems. We define and study an Affine OCDM (A-OCDM) system in which a chirp parameter is adapted to enable maximum diversity offered by frequency selective channels. Our proposed system also reduces implementation complexity by eliminating the need for precoding, compared to linear constellation precoded OCDM. Corroborating simulations are provided to show that A-OCDM also preserves OCDM systems' resilience against interference offered by spreading.
