<p>A method and an apparatus for confirming downlink synchronous code of single-sampled data in TD-SCDMA are provided in the present invention. The method for confirming downlink synchronous code includes: performing sliding correlation calculation on the received sub-frame data and the 32 local downlink synchronous codes, and obtaining 32 sets of correlation values; computing the power value of each correlation value in said 32 sets of correlation values, and obtaining 32 sets of correlation power values; processing each set of correlation power values in said 32 sets of correlation power values respectively, and obtaining corresponding correlation peak values; reserving the correlation peak values that are greater than the first preset threshold from the obtained correlation peak values, and recording the corresponding downlink synchronous code and its location. The method and apparatus for confirming the downlink synchronous code in TD-SCDMA of the present invention reduce computational complexity and save hardware resources as well as guaranteeing an effective cell searching performance, and can well adapt to the cell searching of the TD-SCDMA system.</p> |
