| Abstract(in English) | In this paper, we propose a new desired signal power to undesired signal power ratio estimation (DURE) method for the downlink frame of dynamic-parameter-controlled orthogonal frequency and time division multiple access (DPC-OF/TDMA) and a new subcarrier arrangement of the orthogonal frequency division multiplexing (OFDM) symbols used for DURE. The proposed subcarrier arrangement enables no interference between the signals transmitted form the adjacent cells by employing orthogonal sequence codes, and thus, we can distinguish the desired signal from the undesired ones and estimate DURE accurately. Moreover, we propose another DURE method. We evaluated the effectiveness of the proposed methods by computer simulation in multi cell environment. |
