On Low-Resolution ADCs in Practical 5G Millimeter-Wave Massive MIMO Systems
Jiayi Zhang, Lnglong Dai, Xu Li +2
Nowadays, millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems is a favorable candidate for the fifth generation (5G) cellular systems. However, a key cha…
Multipair Massive MIMO Two-Way Full-Duplex Relay Systems with Hardware Impairments
Ying Liu, Xipeng Xue, Jiayi Zhang +3
Hardware impairments, such as phase noise, quantization errors, non-linearities, and noise amplification, have baneful effects on wireless communications. In this paper, we investi…
Novel Device-to-Device Discovery Scheme based on Random Backoff in LTE-Advanced Networks
Jiayi Zhang, Likai Deng, Xu Li +3
Device-to-Device (D2D) discovery is a key enabler of D2D communications for the direct exchange of local area traffic between proximity users (UEs) to improve spectral efficiency.…
On High-Order Capacity Statistics of Spectrum Aggregation Systems over - and - shadowed Fading Channels
Jiayi Zhang, Xiaoyu Chen, Kostas P. Peppas +2
The frequency scarcity imposed by fast growing demand for mobile data service requires promising spectrum aggregation systems. The so-called higher-order statistics (HOS) of the ch…
