Implement Blind Interference Alignment over Homogeneous 3-user 2x1 Broadcast Channel
Qing F. Zhou, Q. T. Zhang, Francis C. M. Lau
This paper first studies the homogeneous 3-user 2x1 broadcast channel (BC) with no CSIT. We show a sufficient condition for it to achieve the optimal 3/2 degrees of freedom (DoF) b…
Diophantine Approach to Blind Interference Alignment of Homogeneous K-user 2x1 MISO Broadcast Channels
Qing F. Zhou, Q. T. Zhang, Francis C. M. Lau
Although the sufficient condition for a blindly interference-aligned (BIA) 2-user 2x1 broadcast channel (BC) in homogeneous fading to achieve its maximal 4/3 DoF is well understood…
Performance Analysis of Protograph-based LDPC Codes with Spatial Diversity
Yi Fang, Pingping Chen, Lin Wang +2
In wireless communications, spatial diversity techniques, such as space-time block code (STBC) and single-input multiple-output (SIMO), are employed to strengthen the robustness of…
Implementation Of Decoders for LDPC Block Codes and LDPC Convolutional Codes Based on GPUs
Yue Zhao, Francis C. M. Lau
With the use of belief propagation (BP) decoding algorithm, low-density parity-check (LDPC) codes can achieve near-Shannon limit performance. In order to evaluate the error perform…
