Dictionary Learning Based Sparse Channel Representation and Estimation for FDD Massive MIMO Systems
Downlink beamforming in FDD Massive MIMO systems is challenging due to the large training and feedback overhead, which is proportional to the number of antennas deployed at the base station, incurred by traditional downlink channel estimation techniques. Leveraging the compressive sensing framework, compressed channel estimation algorithm has been applied to obtain accurate channel estimation w...
متن کاملchannel 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...
Channel Estimation for Fdd Massive Mimo Using Bayesian Estimator
Massive MIMO systems that for a cellular network, the channel from user equipment to a base station is composed of few grouped paths in space. With a very large antenna array, signals can be observed under extremely sharp regions in space. In the FDD mode, each BS sends a downlink training matrix to its served UEs which estimates the desired channel based on the downlink measurements and feeds ...
متن کاملHierarchical Sparse Channel Estimation for Massive MIMO
The problem of wideband massive MIMO channel estimation is considered. Targeting for low complexity algorithms as well as small training overhead, a compressive sensing (CS) approach is pursued. Unfortunately, due to the Kroneckertype sensing (measurement) matrix corresponding to this setup, application of standard CS algorithms and analysis methodology does not apply. By recognizing that the c...
متن کاملChannel Estimation for TDD/FDD Massive MIMO Systems with Channel Covariance Computing
In this paper, we propose a new channel estimation scheme for TDD/FDD massive MIMO systems by reconstructing uplink/downlink channel covariance matrices (CCMs) with the aid of array signal processing techniques. Specifically, the angle information and power angular spectrum (PAS) of each multi-path channel is extracted from the instantaneous uplink channel state information (CSI). Then, the upl...
