自适应 Turbo 频域信道估计与低复杂度 Turbo 空频均衡 (TSFE) 相结合，用于单载波 (SC) 多用户检测。简化的 Turbo 递归最小二乘 (RLS) 信道估计算法提供了与其完全复杂版本几乎相同的性能，并且大大降低了复杂性。通过 PSK 调制，简化的 Turbo RLS 信道估计简化为 Turbo LMS 信道估计。简化的 Turbo RLS 信道估计具有较低的训练开销，其性能可与具有完美信道状态信息 (CSI) 的情况相媲美。
Adaptive turbo frequency-domain channel estimation is incorporated with low complexity turbo space-frequency equalization (TSFE) for single-carrier (SC) multi-user detection. The simplified turbo recursive least square (RLS) channel estimation algorithm provides nearly the same performance as its full complexity version, with a tremendous complexity reduction. With PSK modulations, the simplified turbo RLS channel estimation reduces to turbo LMS channel estimation. With a low training overhead, the simplified turbo RLS channel estimation provides a performance comparable to the case with perfect channel state information (CSI).
