Abstract:

For the problem of ambiguous acquisition of multipath binary offset carrier (BOC) signals, a method which is based on the Rake model is proposed. Firstly, the received signals are separated and pass through the Rake model with carrier phase estimation. Then the approximate single-path signal is gotten by using the method of the maximum ratio combining. Finally, BOC signals are captured by the method of relevant reconstruction with the compensation of frequency offset and its detail theory is given. Theoretical analysis and computer simulations show that, under the same conditions, this method has the advantage of high accuracy and is easy to be implemented compared with other methods, and the higher the modulation order, the better the performance.
