The channel estimate and carrier frequency offset (CFO) acquisition are two essential bases for multiple-input-multiple-output (MIMO) orthogonal division multiplexing (OFDM) techniques. In high-mobility scenario, the fast time varying serious Doppler shift will make tracking CFO estimation much more challenging. this paper, achievable limits of joint basis expansion-model (BEM)-based derived in terms Bayesian Cramer-Rao lower bound (BCRLB) to reveal impact dependent factors, like pilot BEM...
Summary GPGPU‐powered supercomputers are vital for various science and engineering applications. On each cluster node, the GPU works as a coprocessor of CPU, computing task runs alternatively on CPU GPU. Due to this characteristic, traditional scheduling strategy tends result in significant workload imbalance underutilization GPUs. We design an adaptive alleviate such underutilization. Our proposes logically treats all GPUs whole. Every node maintains local information table Once call...
A new method through rotation matrix in MIMO system is proposed this paper, which increases the distance of code-words and decreases pair wise error probability. Compared with some traditional ways, bandwidth-efficient. detection MMSE-ML used for simple algorithm. The computer simulation results confirmed that high SNR, can efficient decrease multi-user interference without any coding or bandwidth expansion. Using detection, 3.2E-3 BER reached at 22 dB SNR.
