Robust Speech Spectra Restoration against Unspecific Noise Conditions for Pitch Detection (2008)
XU, Xin, HAYASAKA, Noboru, MIYANAGA, Yoshikazu
This paper proposes a new algorithm named Adaptive Running Spectrum Filtering (ARSF) to restore the amplitude spectra of speech corrupted by additive noises. Based on the pre-hand noise estimation,...
PRADABPET, Chusit, YOSHIZAWA, Shingo, MIYANAGA, Yoshikazu, DEJHAN, Kobchai
In this paper, we propose a new PAPR reduction by using the hybrid of a partial transmit sequences (PTS) and an adaptive peak power reduction (APPR) methods with coded side information (SI)...
VLSI Implementation of a Complete Pipeline MMSE Detector for a 4 x 4 MIMO-OFDM Receiver (2008)
YOSHIZAWA, Shingo, YAMAUCHI, Yasushi, MIYANAGA, Yoshikazu
This paper presents a VLSI architecture of MMSE detection in a 4×4 MIMO-OFDM receiver. Packet-based MIMO-OFDM imposes a considerable throughput requirement on the matrix inversion because of strict...
