Down-sampling filter is employed to obtain 4:2:0 chroma format and up-sampling filter is used for display. Currently, the existing algorithms are processed in spatial domain. In this paper, a frequency domain based down-sampling and up-sampling filter is proposed. With this algorithm, more original information can be preserved and aliasing can be avoided in chrominance components. Simulation results...
A high peak-to-average power ratio (PAPR) makes the orthogonal frequency division multiplexing (OFDM) based wireless local area networks (WLANs) sensitive to non-linear distortion in the transmission. The companding transform approach is a very attractive technique to reduce PAPR, but large PAPR reduction leads to a high bit-error rate (BER) by the available companding transform techniques. In this...
