A space-time coding approach for RFID MIMO systems
This paper discusses the space-time coding (STC) problem for RFID MIMO systems. First, a mathematical model for this kind of system is developed from the viewpoint of signal processing, which makes it easy to design the STC schemes. Then two STC schemes, namely Scheme I and Scheme II, are proposed. Simulation results illustrate that the proposed approaches can greatly improve the symbol-error r...
متن کاملSpace Time Coding for Mimo Systems
With space-time codes (STC) the same information is transmitted in appropriate manner simultaneously from different transmit antennas to obtain transmit diversity. The main idea of transmit diversity is that if a message is lost in a channel with probability p and we can transmit replicas of the message over n independent such channels, the loss probability becomes p. Using diversity, more reli...
متن کاملAn adaptive iterative receiver for space-time coding MIMO systems
An adaptive iterative receiver for layered spacetime coded (LSTC) systems is proposed. The proposed receiver, based on a joint adaptive iterative detection and decoding algorithm, adaptively suppresses and cancels co-channel interference. The LMS algorithm and maximum a posteriori (MAP) algorithm are utilized in the receiver structure. A partially filtered gradient LMS (PFGLMS) algorithm is als...
متن کاملAntenna Selection for MIMO Systems with Space - Time Coding
Multiple-Input multiple-output (MIMO) technology is capable of enhancing capacity and coverage of wireless links. Implementation of MIMO devices is intricate because of the increased number of radio frequency chains (one for each antenna element). Antenna selection is one attractive approach to mitigate this requirement. It only utilizes an optimal subset of all available antennas, adapting it ...
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...
