Space 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 Efficient Space-Time Coding Scheme for Time Dispersive MIMO Channels
In this paper, we introduce an efficient space-time coding scheme for time dispersive Multiple-Input Multiple-Output (MIMO) channels. Channel layering and Orthogonal Frequency Division Multiplexing (OFDM) technique are used in the proposed scheme. The proposed scheme is based on maximizing the distance between any two codewords. This is done by inserting an optimized phase shifts between the sy...
متن کاملMIMO Channels and Space-Time Coding
Outline: • Capacity of MIMO Channels: We discuss the information theo-retic bases for the capacity arguments of MIMO channels and present fundamental results and methods. • Channel Modeling and Realizable Capacity: We discuss simple ray-tracing channel models and study the capacity of these artificially generated channels. Basic conclusions on the behavior of real-world MIMO channels are drawn....
متن کاملAn Efficient Adaptive Space Time Coding Scheme for MIMO-OFDM Systems
Within the framework of the Stingray Project, a Hiperman compatible MIMO system, three architectures with different rate-one Space-Time Codes (STC) are presented and their performance assessed. Viewing beam-forming and Alamouti as the two extreme cases of the trade-offs between performance/ complexity/feedback-requirements, an efficient scheme is proposed that reduces complexity and feedback re...
متن کاملA numerical scheme for space-time fractional advection-dispersion equation
In this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. We utilize spectral-collocation method combining with a product integration technique in order to discretize the terms involving spatial fractional order derivatives that leads to a simple evaluation of the related terms. By using Bernstein polynomial basis, the problem is transformed in...
