Abstract
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.
