Joint blinding estimation of the spread-spectrum sequence and information sequence for short-code DS-SS signal
The problem of joint blinding estimation of the spread-spectrum sequence and information sequence of DS-SS signals was studied.First,the received signal is divided into double-symbol-period-length temporal vectors,with one-symbol-period overlapping,accumulates of these vectors one by one to form the...

| description | The problem of joint blinding estimation of the spread-spectrum sequence and information sequence of DS-SS signals was studied.First,the received signal is divided into double-symbol-period-length temporal vectors,with one-symbol-period overlapping,accumulates of these vectors one by one to form the signal matrix.Then,an operation of singular value decomposition (SVD) may be applied to the matrix to estimate the spread-spectrum and information sequence jointly.The algorithm makes use of a single vector space to estimate the spread-spectrum sequence and information sequence blindly,without known the desynchronization time,even in low SNR.The algorithm is not only unaffected by the type of spreading spectrum sequence,but also avoids to solving the problem of the phase ambiguity when use two vectors to reconstruct spread-spectrum sequence,which based on EVD blinding estimate algorithm.So it heightens the validity of blinding estimation.At last,simulation results demonstrate the validity of the algorithm. |
