Abstract(in English) | In DPC-OF/TDMA (Dynamic Parameter Controlled OF/TDMA), signal interference that comes from other cells is one of serious problems for down link, because adjacent cells a common frequency band. To estimate desired signal power to undesired signal power ratio (DUR) accurately is one of important issues to solve. Our research group has proposed to insert spread code such as cyclic shifted M-sequence or Walsh sequence in frequency domain as DUR estimation symbol. But the estimation accuracy is not enough. In this paper, in order to estimate DUR acculately, we propose to use a new sequence that adds all 1 data in frequency domain to phase difference with a procedure in addition to spread code. The new sequence can insert the spread code separately and super-impose to the code. The new code become pulse data from the viewpoint of time domain and the generation timing of timing can change by changing the phase added to the sequence freely by the order of cellular zone. In this paper, we explain the new DUR estimation method and evaluate improvement of estimated result by computer simulation. |
