| Abstract(in English) | This paper investigates a tradeoff between peak-to-average power ratio (PAPR) and achievable capacity of the proposed PAPR reduction method based on clipping and filtering (CF) for the block diagonalization-based multiuser multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) transmission in frequency-selective faded channel. Assuming that the number of total receiver antennas is smaller than that of the transmitter antennas, we introduce virtual streams used for the PAPR reduction only and the precoding matrix for these virtual streams which does not cause interference from the virtual streams to the actual data streams. Since the interference caused by the clipping operation is concentrated on the virtual streams and that to the actual data stream is restricted as a result, the proposed method can largely improve the channel capacity compared to the conventional clipping and filtering method. Simulation results elucidate that the proposed method shows that the PAPR is greatly reductive as the number of frequency blocks increases. |
