an acquisition scheme using negative-slope saw-tooth-waveform matching was proposed.The scheme obtained the sub-optimal estimation performance by utilizing the characteristic of multipath profile.In the proposed scheme
the slope of saw-tooth waveform was analyzed to achieve unbiased estimation in NLOS environment
and the theoretical solution of mean-absolute error(MAE) was derived.Simulations verify the outstanding performance of this scheme in NLOS and low signal-to-noise ratio(SNR) environment.
