Effect of mutual coupling and antenna correlation on MIMO system in three-dimensional spatial channel models by Jie ZHOU, Jing-feng CHEN, Lin QIU, Kikuchi HISAKAZU

“…A channel model for frequency nonselective Rayleigh fading MIMO channel was set up and the channel model setting was extended to three-dimensional space.The mutual coupling between antenna elements was analyzed based on the equivalent network model of the multiple-antenna.The general spatial correlation expressions of channel model with the impact of mutual coupling were derived in the three-dimensional spatial channels.When the receivers were different antenna arrays,the effect of the angular parameters associated with the mean azimuth of arrival(MAOA),azimuth spread(AS),meant elevation of arrival(MEOA)and elevation spread(ES)on the MIMO system capacity was investigated.Numerical results verifiy the impact of different angle spread on spatial correlation with the mutual coupling and indicate that the system capacity is more dependent on the MAOA and MEOA than the AS and ES.…”

Partial interference elimination based retrospective interference alignment scheme in the downlink MIMO broadcast channel by Jingfu LI, Wenjiang FENG, Wenshou WANG, Weiheng JIANG, Chonghai YANG

“…For interference networks, the degree of delay (DoD) was proposed to quantify the information delay among traditional interference alignment (IA) schemes.It indicated that networks suffer from the issue of latency caused by IA schemes.Herein, for the MIMO downlink broadcast channel (BC), the partial interference elimination based retrospective interference alignment scheme (PIE-RIA) was put forward.In the scheme, relay technique was adopted to eliminate partial interference signals so that part of desired symbols could be decoded promptly in user sides.Meanwhile, in the last slot, the eliminated signals could be regenerated in base station side with the retrospective interference alignment (RIA) scheme .The simulation results show that PIE-RIA scheme maintains degree of freedom (DoF) gain of RIA scheme and in the meantime, achieves lower DoD than the other schemes.…”
