- W4306787431 abstract "The problem of pseudo-noise (PN) sequence estimation of direct sequence spread spectrum (DS-SS) signals is studied in this paper. A new estimation method for PN sequence is given based on improved propagator. The algorithm could estimate the spread spectrum sequence and the signal out-of-step time by using the signal subspace. Compared with the eigenvalue decomposition (EVD) method, the estimation accuracy of the out-of-step time is improved and the amount of calculation is effectively reduced. Computational complexity and performance comparisons are made between the new method and the existing algorithm. Simulation results show that the method can provide a good estimation, even the received signal is below the noise level." @default.
