A low complexity carrier phase estimation (CPE) for 16-QAM systems is investigated in this letter. First, we propose a single-stage CPE algorithm based on the error function calculation. In this CPE algorithm, we define an error function and use the four error function values corresponding to four test phase angles ($-\pi $ /4, $-\pi $ /8, 0, and $\pi $ /8) to directly calculate the optimal phase...
The vector dirty paper coding (DPC) can achieve rate region for multicell cooperation system. Conventional DPC implementation approach suffer the capacity loss due to quantization which lead to modulo loss. In this paper, we proposed a vector DPC transmission scheme with non-binary LDPC codes and low density generator matrix based quantizer for multicell processing. And the random coding based proof...
This paper presents an efficient spatial interpolation scheme for spatial scalability in the joint scalable video model (JSVM) which defines a scalable extension on top of the H.264/AVC. In order to increase coding efficiency of JSVM, we adopt a simplified up-sampling filter. It is only used to magnify the chroma components of an image due to the less importance of them. Simulation results show that...
Scalable video coding is a new emerging standard, which provides scalability at the bit stream level with good compression efficiency and allowing free combinations of spatial, temporal and quality scalability. In current working draft (WD), a uniform up-sampling filter is employed to interpolate the base layer frames. This technique achieves high interpolated precision for both luma component and...
A precoding technique is proposed for single-carrier block transmission with cyclic prefix (CP) insertion over inter-symbol interference (ISI) channels. The precoder is based on circular convolution that can be implemented in the frequency domain, so that the detection complexity is kept low using the linear-minimum-mean-square-error (LMMSE) frequency domain equalization (FDE) technique. The precoder...
