| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper investigates the throughput performance of turbo coded single-carrier transmission with our previously reported frequency-domain puncturing. In the frequency-domain puncturing, after applying the discrete Fourier transform (DFT) to the transmission coded symbols, some of the frequency components (spectrum) are punctured to increase the equivalent coding rate. The difference compared to conventional bit-level time-domain puncturing is that the frequency-domain puncturing can transmit all the coded bits. Therefore, the coding gain is expected to increase compared to that for time-domain puncturing. The cost is the inter-symbol interference (ISI). Frequency-domain turbo equalization at the receiver is employed to mitigate the ISI. For more concrete performance evaluation, we extended the proposed method to the case with 16QAM modulation in addition to the QPSK. From the simulation results, we show that the frequency-domain puncturing can increase the throughput compared to the case only using time-domain puncturing. Throughput gain is more observed with lower order modulation such as QPSK rather than 16QAM. In the frequency-selective fading channel, the performance gain by using the frequency-domain puncturing is decreased, which implies that the channel dependent scheduling may be beneficial for obtaining the potential gain of the frequency-domain puncturing in frequency-selective fading channel. | |
