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...
Implementation of a Real-Time Satellite Channel Simulator
This paper is focused upon implementation aspects of a real-time simulator applicable to narrowband land mobile satellite channels. The satellite channel is mainly affected by shadowing. If a direct signal component exists (line of sight (LOS) conditions), the channel is in a so-called good/clear state and the probability density function (pdf) of the signal amplitude is Rician distributed. The...
متن کاملHigh-resolution compressive channel estimation for broadband wireless communication systems
Broadband channel is often characterized by a sparse multipath channel where dominant multipath taps are widely separated in time, thereby resulting in a large delay spread. Accurate channel estimation can be done by sampling received signal with analog-to-digital converter (ADC) at Nyquist rate and then estimating all channel taps with high resolution. However, these Nyquist sampling-based met...
متن کاملInterference Mitigation Techniques for Broadband Satellite Systems
This paper presents an overview of possible interference mitigation techniques aiming at increasing the system capacity of broadband multimedia satellite systems. A multi-star network topology using a bent-pipe transparent satellite is assumed. After a general overview, the paper concentrates on the assessment of Linear Precoding techniques for increasing the potential system capacity on the Fo...
