<p>The present invention provide a multi-path search method of code-division multiple-access system, first calculate the received signal power delay function, select some large power peaks, then compare and interpolate threshold of the selected peaks, determine the multi-path position and power last determine the multi-path delay according the interpolation result. Compare the common art the present invention would ensure improve precision of the multi-path search greatly under the circumstances of maintaining the complicacy of calculation, the precision of the multi-path search could be 1/4 chip precision, 1/8 chip precision, even could be 1/16 chip precision; meanwhile, the present invention do not need to apply the before and after threshold following modular, and do not need the complex following arithmetic, greatly simplify the complicacy of RAKE receiver and the complicacy of management of multi-path distribution; further the present invention is adopted in various base stations and mobile terminals in code-division multiple-access system.</p> |
