| Abstract(in English) | It's research target more important that combined OFDM modulation with LDPC codes in digital wireless communication systems. However, there is required high-throughput for baseband processing in hardware design, by increasing number of OFDM carrier and LDPC code length. In this paper, we propose high-throughput architectures for LDPC coded OFDM baseband processor. For improvement of decoding quality, we disperse the burst errors by interleaving method. And our architectures can realize high-throughput baseband processor using 1024-point FFT circuit based memory-based architecture and full parallel LDPC decoder. As a result, we can achieve high-throughput more than 550Mbps by frequency 100MHz. |
