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...
Time Domain Precoding for MIMO-OFDM Systems
Broadband multiple-input multipleoutput (MIMO) communication systems using spatial multiplexing are facing multi-stream interference (MSI) from the transmit antennas and intersymbol interference (ISI) due to the time-dispersive nature of the channel. Appropriate detection requires the minimization of both sources of interference, usually at the receiver. Orthogonal frequency division multiplexi...
متن کاملOverall PAPR Reduction for MIMO OFDM Systems
Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems have been receiving a great attention as one of the solutions for achieving high speed, efficient, and high quality of service wireless communications. However, the main drawback of MIMO OFDM systems is high Peak to Average Power Ratio (PAPR) because of its sensitivity to the nonlinear distortions in...
متن کاملPerformance of regression-based precoding for multi-user massive MIMO-OFDM systems
We study the performance of a single-cell massive multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) system that uses linear precoding to serve multiple users on the same time-frequency resource. To minimize overhead, the channel estimates at the base station are obtained via comb-type pilot tones during the training phase of a time-division duplexing system. ...
متن کاملGMD-Based Hybrid Precoding For Millimeter-Wave Massive MIMO Systems
Hybrid precoding can significantly reduce the number of required radio frequency (RF) chains and relieve the huge energy consumption in mmWave massive MIMO systems, thus attracting much interests from academic and industry. However, most existing hybrid precoding schemes are based on singular value decomposition (SVD). Due to the very different subchannel signal-to-noise ratios (SNRs) after SVD...
