The modified Discrete Fourier Transform (MDFT) filter bank is a Nearly Perfect Reconstruction (NPR) system based on pseudo-QMF filter bank. Due to its complex input processing and fast efficient algorithms (FFT), MDFT filter bank is particularly suitable for multicarrier modulation applications. In this paper we apply the MDFT filter bank into multicarrier(More)
Digital Video image scaling is a full-fledged technology, and can be found everywhere in our daily life. However, the appearance of HDTV brought some problem between the new display devices and the old video signals. In this paper, a novel method of nonlinear scaling is proposed, aim to overcome the compatibility problem. Different from traditional linear(More)
One of the challenges of Orthogonal Frequency Division Multiplexing (OFDM) is its high Peak-To-Average Power Ratio (PAPR) which may lead to system performance degradation due to low power efficiency in the presence of nonlinear power amplification. All existed PAPR reduction methods in the literature such as clipping, phase shift and compand transform are(More)
