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...
Channel Estimation Technique for MIMO-OFDM over Fast Fading Channels
A channel estimation method for multiple input multiple output (MIMO)-OFDM with fast fading channels is proposed to increase estimation quality and reduce the computational complexity. Specifically, we use a space-time correlation between channel coefficients, and compensate the ICI term. Since ICI compensation can be obtained without any pilot symbols for target OFDM block, our proposal is pra...
متن کاملA Low Complexity Adaptive Channel Estimation Scheme for OFDM Systems over Frequency-selective Fading Channels ?
Channel estimation is one of the key technologies in Orthogonal Frequency Division Multiplexing (OFDM) systems, which has received more and more consideration. At first, the scheme uses the idea of matrix diagonalization to improve the Minimum Mean Square Error (MMSE) estimation method, making it to greatly reduce the complexity while maintain the estimate convergence. Then, an adaptive scheme ...
متن کاملMMSE Equalization for OFDM Systems over Frequency-Selective Fading Channels
Channel estimation is one of the key technologies in Orthogonal Frequency Division Multiplexing (OFDM) systems, which has received more and more consideration. A modified Minimum Mean Square Error (MMSE) is proposed and simulated by MATLAB over a frequency-selective fading channel. Comparing with the conventional MMSE, this algorithm has the advantage of low complexity. Meanwhile, it shows litt...
متن کاملBER Estimation of OFDM System over Frequency Selective Fading Channels
OFDM system is promising technology for high speed data communication in wireless media. In this paper OFDM system model is developed over flat fading channel with Additive Gaussian White Noise (AWGN). Initially BER analysis is carried out in OFDM system with the number of sub-carriers ‘N’ using M-ary PSK and M-ary QAM. Analysis is carried out with the number of sub-carriers (N=64) with Rayleig...
