| Abstract(in English) | A software defined radio (SDR) implementation of OFDM transceiver based on dynamic spectrum access (DSA) is proposed, which best utilizes a parallel processing ability of GPU to cope with huge computational cost. Convolutional coding process and Viterbi decoding process, which inherently require sequential processing, are reorganized into OFDM symbol basis to enable parallel processing. Then, Interleaving, Sub-carrier modulation, and mapping processes, which have an identical processing structure, are integrated into single process to reduce processing overhead. Moreover, the number of OFDM symbols to be processed in parallel, which is required for enabling real-time processing, has been derived, Consequently, 14 or more OFDM symbols and 21 or more OFDM symbols should be processed in parallel at a transmitter and at a receiver, respectively. |
