Frequency-Domain Response Based Timing Synchronization: A Near Optimal Sampling Phase Criterion for TDS-OFDM
Zhen Gao, Chao Zhang, Yu Zhang +1
In time-domain synchronous OFDM (TDS-OFDM) system for digital television terrestrial multimedia broadcasting (DTMB) standard, the baseband OFDM signal is upsampled and shaping filt…
Channel Estimation for mmWave Massive MIMO Based Access and Backhaul in Ultra-Dense Network
Zhen Gao, Linglong Dai, Zhaocheng Wang
Millimeter-wave (mmWave) massive MIMO used for access and backhaul in ultra-dense network (UDN) has been considered as the promising 5G technique. We consider such an heterogeneous…
Spatially Common Sparsity Based Adaptive Channel Estimation and Feedback for FDD Massive MIMO
Zhen Gao, Linglong Dai, Zhaocheng Wang +1
This paper proposes a spatially common sparsity based adaptive channel estimation and feedback scheme for frequency division duplex based massive multi-input multi-output (MIMO) sy…
Channel Estimation for Millimeter-Wave Massive MIMO with Hybrid Precoding over Frequency-Selective Fading Channels
Zhen Gao, Linglong Dai, Chen Hu +1
Channel estimation for millimeter-wave (mmWave) massive MIMO with hybrid precoding is challenging, since the number of radio frequency (RF) chains is usually much smaller than that…
Near-Optimal Signal Detector Based on Structured Compressive Sensing for Massive SM-MIMO
Zhen Gao, Linglong Dai, Chenhao Qi +2
Massive spatial modulation (SM)-MIMO, which employs massive low-cost antennas but few power-hungry transmit radio frequency (RF) chains at the transmitter, is recently proposed to…
