摘要

提出了一种基于二阶Reed-Muller序列的下行通信方法，该方法推广了正交CDMA中使用的Walsh序列。在我们的方法中，编码发生在芯片级(即我们使用1的扩展因子)，不同的用户没有正交化。我们的解码算法借鉴了用于压缩感知的信号的快速重建工作。该算法允许低复杂度的多用户检测。

Enhanced CDMA communications using compressed-sensing reconstruction methods

We propose a simple method for downlink communications based on second order Reed-Muller sequences which generalize the Walsh sequences that are used in orthogonal CDMA. In our approach, coding occurs at the chip level (i.e. we use a spreading factor of 1) and different users are not orthogonalized. Our decoding algorithm is borrowed from work on fast reconstruction of signals for compressed-sensing. This algorithm allows for low-complexity multiuser detection.
