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...
Signal Processing for Future MIMO-OFDM Wireless Communication Systems
The combination of multiple-input multiple-output (MIMO) technol ogy and orthogonal frequency division multiplexing (OFDM) is likely to provide the air-interface solution for future broadband wireless sys tems. A major challenge for MIMO-OFDM systems is the problem of multi-access interference (MAI) induced by the presence of multiple users transmitting over the same bandwidth. Novel signal p...
متن کاملLinear Approximation Signal Detection Scheme in MIMO-OFDM Systems
In this paper, a linearly approximate signal detection scheme is proposed in multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems. The huge MIMO-OFDM system, which uses many transmit antennas and high order modulation, requires a detection scheme at the receiver with very low complexity for practical implementation. In the proposed detection scheme, one ...
متن کاملDiversity Management in MIMO-OFDM Systems
Over the last decade, a large degree of consensus has been reached within the research community regarding the physical layer design that should underpin state-of-the-art and future wireless systems (e.g., IEEE 802.11a/g/n, IEEE 802.16e/m, 3GPP-LTE, LTE-Advanced). In particular, it has been found that the combination of multicarrier transmission and multiple-input multiple-output (MIMO) antenna...
متن کاملEnhanced Information Throughput in MIMO-OFDM based systems using Fractional Sampling and Iterative Signal Processing
Herein, we study the feasibility of enhanced information throughput capability of Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) based wireless communication systems in the context of increasing wireless capacity demand. The concept of Fractional Sampling (FS) is exploited for this purpose to take advantage of diversity created due to it. Furthermore, a no...
