Parallel code phase search device and method for realizing parallel code phase search

The invention discloses a parallel code phase search device and a method for realizing parallel code phase search. The method comprises the following steps: correspondingly jumping a received time-domain correlation result after inverse Fourier transform through a preset number of jump sequences to obtain corresponding jump correlation results; coherently accumulating the jump correlation results to obtain corresponding coherent accumulation results; performing modulo operation on the coherent accumulation results to obtain corresponding modulo operation results; and obtaining a maximum item in the modulo operation results through comparison of all the modulo operation results, and taking the jump sequence modulo operation result with the maximum item as the output to carry out phase search. In the technical scheme of the invention, inverse Fourier transform is carried out before coherent accumulation, which reduces the complexity of parallel code phase search, and realizes phase search under the condition of
