channel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Pilot signal design for coordinated transmission in massive MIMO systems
Massive multi-input multi-output (m-MIMO) and coordinated multipoint transmission (CoMP) are quite feasible techniques to improve the spectral efficiency in next generation wireless communication systems. It is of great concern to accurately estimate channel state information (CSI) of all base stations (BSs) involved in CoMP. Muting may be applied to improve the CSI estimation, which can reduce...
متن کاملCoding For MIMO Wireless Systems
MIMO wireless systems have received a great deal of attention recently, in part due to the promise of increased throughput, extended range, and improved reliability. Achieving the gains of the MIMO channel requires coding that can take advantage of these channel resources. This work studies the performance of different concatenated space-time coding and outer channel coding and develops some pr...
متن کاملDual Polarized Omnidirectional Array Element for MIMO Systems
The capacity of a Multiple-Input Multiple-Output (MIMO) system depends on the channel matrix as well as the Signal-to-Noise ratio. A novel dualpolarized planar channel model with one or two scattering rings is used to compare the capacity of different antenna arrays. The correlation between channel matrix elements of the presented channel model and the statistical Kronecker model is also compar...
متن کاملSymbol-multicast mutual coding for massive MIMO broadcasting
New transmit mutual coding for MIMO broadcasting is proposed. The proposed coding is based on wireless transmission over symbol multicasting to independent and uncoordinated terminals in the downlink. The motivation of proposing symbol-multicast is the fact that in digital communication the transmission is based on a finite alphabetic. Therefore, it would be possible to multicast symbols to rec...
