摘要

针对开环欠定MIMO信道中稀疏空间码(SSC)的传输，提出了一种新的译码算法。基跟踪检测器算法与和积算法相结合，实现了基于LDPC的外码和基于SSC的内码的迭代译码。此外，针对上行MIMO信道，提出了一种利用SSC码进行多用户检测的新思路。

Iterative decoding and multiuser communication using sparse space codes for MIMO channels

We propose a new decoding algorithm for sparse space codes (SSC) transmission in an open-loop under-determined MIMO channel. The basis pursuit detector algorithm is combined with the sum-product algorithm to facilitate an iterative decoding using the LDPC based outer codes and the SSC based inner codes. In addition, a novel idea on multiuser detection using SSC codes is presented for an uplink MIMO channel.
