Orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO system
Published 2017-07-01“…Due to the high cost and power consumption of some mixed signal components at mmWave frequencies,the conventional full digital precoding technique encounters the problem of high hardware complexity.Consequently,the hybrid analog-digital precoding architecture has attracted the attentions from both academy and industry.Based on this,an orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO systems was proposed,which utilized the orthogonality of beam codebook to design the analog beamforming vector of each radio frequency (RF) chain in parallel.As a result,the large computational complexity of the conventional orthogonal matching pursuit (OMP) algorithm and the hardware complexity could be greatly reduced.…”

Dynamic spectrum access method for femtocells in LTE
Published 2015-01-01“…Dynamic spectrum access method for femtocells in LTE using cognitive radio method to meet the communication requestions was investigated.An uplink sensing method was proposed.By this method,femtocells could not only identify occupied spectrums but also identify service categories of those spectrums.A dynamic spectrum assess method of power control and frequency hopping for femtocells that ensured a low pre-definable performance impact to macro users was proposed.The femtocell could adopt power control to access the spectrum that carried data service while adopt frequency hopping to access the spectrum that carried voice service.Simulation results show that the downlink throughput of the femtocell can be significantly increased by using proposed spectrum access method.…”
