... CFO, SFO and channel distortions was examined and explored to develop a turbo joint channel estimation, synchroniza- tion, and decoding scheme and a vector RLS-based joint CFO, SFO, and CIR tracking ... to establish their initial values for the turbo joint tracking of CIR, CFO, and SFO. The coarse CIR estimation is performed by using the vector RLS algorithm and the first l...
