摘要：
In this paper, noncoherent equalization is combined with multiple receive antennas. The resulting noncoherent space-time equalization (NSTE) schemes are analyzed and compared with the corresponding coherent receivers. In particular, noncoherent linear equalization (NLE) and noncoherent decision-feedback equalization (NDFE) are considered. For both NLE and NDFE novel approximations for the signal-to-distortion ratio (SDR) are given and verified by simulations. It is shown that NSTE can suppress interfering users and exploit diversity as effectively as coherent STE. However, NSTE is more robust against channel phase variations than coherent STE combined with synchronization.
