Orthogonal Space-Time Block Codes in Vehicular Environments: Optimum Receiver Design and Performance Analysis
We consider orthogonal space-time block codes (OSTBC) in vehicular environments, where the channels are nonidentically distributed. It is shown that the nonidentical channel statistics lead to nonidentical channel estimation errors, which consequently affect the performance and even the existing receiver structure of OSTBC. We show that the conventional symbol-by-symbol (SBS) decoder of OSTBC i...
متن کاملOrthogonal Space-Time Block Codes
in this paper, we provide a blind adaptive channel estimation method for decoding of orthogonal space-time block codes (OSTBC), which is built on the minimizing of an unconstrained cost function. The global minima of the cost function are analyzed. Both LMS and RLS algorithm realizations are given. Our method can adaptively track the time varying channel and decode transferred symbols without p...

in this paper, we propose space-time block codes based on constituent intersectant orthogonal designs. after channel model is formulated, we studied the space-time block codes from constituent intersectant orthogonal designs. at last we made simulations for the space-time block codes from complex orthogonal design and the space-time block codes from constituent intersectant orthogonal design to...
متن کاملImproved MIMO performance with non-orthogonal space-time block codes
Transmission over Multiple Input Multiple Output (MIMO) radio channels is considered. When multiple Rx antennas are present, one may simultaneously increase the rate and improve performance by optimizing transmit diversity, using nonorthogonal space-time block codes. This improves the performance of MIMO systems considerably, especially when the number of Tx and Rx antennas is small. As an exam...
متن کاملSpace-Time block codes from orthogonal designs
We introduce space–time block coding, a new paradigm for communication over Rayleigh fading channels using multiple transmit antennas. Data is encoded using a space–time block code and the encoded data is split into n streams which are simultaneously transmitted using n transmit antennas. The received signal at each receive antenna is a linear superposition of the n transmitted signals perturbe...
