Performance analysis of MIMO-SESS with Alamouti scheme over Rayleigh fading channels
Self-encoded spread spectrum (SESS) is a novel modulation technique that acquires its spreading sequence from the random input data stream rather than through the use of the traditional pseudo-noise code generator. It has been incorporated with multiple-input multiple-output (MIMO) systems as a means to combat fading in wireless channels. In this paper, we present the analytical study of the bi...
متن کاملPerformance Analysis of MIMO-OFDM System in Rayleigh fading Channel
In this paper we show the performance of MIMOOFDM [1] (Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing) system in Rayleigh Fading Channel [2].MIMO-OFDM system is very popular technique for mobile communication now a day’s .We compares Ergodic and Outage Capacity [3] with taking various numbers of Transmitting and Receiving antennas and various performance measures such...
متن کاملPerformance analysis of coded MIMO OFDM in multipath fading channel
The average bit BER performance of coded MIMOOFDMwith maximum likelihood detection in multipath Nakagami-Rice fadingchannels is analyzed. The upper bound of the BER probability isderived by means of the union bound of the pairwise error probabilities.Asymptotic results for the high SNR region enable to consider the effectof fading correlations and the diversity advantage. Si...
متن کاملA Fast Ml-based Receiver for Mimo Rician Fading Channel
We derive a fast maximum likelihood based (MLB) decoder for a multi-input multi-output (MIMO) Rician fading channel with additive white Gaussian noise (AWGN). The basic idea is to take profit of the Rician channel structure to significantly reduce the search of the optimum vector of symbols by the ML criterion. When channel diversity is low, we obtain bit error rates (BER) which are very close ...
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...
