بهبود روش های تخمین و بازخورد اطلاعات کانال در سیستم های بی سیم massive mimo مبتنی بر zero-forcing beamforming
امروزه به دلیل پیشرفت های چشم گیر تکنولوژی در زمینه ی مخابرات بی سیم و اثبات مزایای فراوان سیستم های چند آنتنه، میزان علاقه به استفاده از آرایه های بزرگ آنتن، هم در فرستنده و هم در گیرنده افزایش یافته است که این سیستم ها به عنوان سیستم های massive mimo شناخته می شوند. افزایش تعداد آنتنها در فرستنده و گیرنده، روشی مناسب برای افزایش ظرفیت شبکه محسوب می شود. با به کار بردن آرایه ای از آنتن ها د...
On The Uplink Throughput of Zero-Forcing in Cell-Free Massive MIMO with Coarse Quantization
The recently proposed Cell-Free massive MIMO architecture is studied for the uplink. In contrast to previous works, joint detection is performed using global CSI. Therefore, we study strategies for transferring CSI to the CPU taking into account the fronthaul capacity which limits CSI quantization. Two strategies for pilot-based CSI acquisition are considered: estimate-andquantize and quantize-...
متن کاملZero-forcing DPC beamforming design for multiuser MIMO broadcast channels
The sum rate maximization in multiuser MIMO broadcast channels is investigated in this paper. We first propose an approach under a total power constraint. Compared with the most related methods in the literature, the proposed method can be easily adapted to a more realistic per-antenna power constraint. Since the power of each antenna is limited individually by the linearity of its power amplif...
متن کاملDistributed Multi-Cell Zero-Forcing Beamforming in Cellular Downlink Channels
For a multiple-input single-output (MISO) downlink channel with M transmit antennas, it has been recently proved that zero-forcing beamforming (ZFBF) to a subset of (at most) M “semiorthogonal” users is optimal in terms of sum-rate, asymptotically with the number of users. However, determining the subset of users for transmission is a complex optimization problem. Adopting the ZFBF scheme in a ...
متن کاملPerformance Comparison of MIMO Systems over AWGN and Rayleigh Channels using OSTBC4 with Zero Forcing Receivers
MIMO (Multiple-input multiple-output) is an antenna technology for wireless communications in which multiple antennas are used at both the transmitter and the receiver. The antennas used at each end of the communications circuit are combined to optimize data speed within the limited radio frequency spectrum. The performance analysis of MIMO system over AWGN and Rayleigh fading channels using OS...
