Improved Method Of Aperiodic Spread Spectrum Acquisition

We refer to the system with non-integer spread ratio as aperiodic spread spectrum acquisition system. In aperiodic spread spectrum system, it is impossible to know the start time of the relevant processing relative to information symbol, so the traditional methods using one whole symbol to related process will cause amplitude of correlation-peak defect when there are positive and negative alternating phenomena between adjacent information symbols. In particular, when there are a large number of consecutive 01 signals in information symbol, the traditional method may cause the correlation peak to be 0. This will make the traditional acquisition method completely ineffective. Therefore, this paper presents an improved method for aperiodic spread spectrum system. It will effectively solve the problem of peak amplitude defect.
