title: Adaptive transmit diversity with orthogonal space-time block coding for telemedicine application.
abstract: Recently an adaptive transmit eigenbeamforming with orthogonal space-time block coding (Eigen-OSTBC) has been proposed. This model was simulated over macrocell environment with a uniform linear array (ULA) at the base station (BS) for next-generation (NG) wireless/mobile network. In this paper, we introduce a telemedicine simulation framework employing the Eigen-OSTBC scheme for the investigation of communication system characteristics in the application of biological data such as electrocardiogram (ECG). The geometrical-based hyperbolically distributed scatterers (GBHDS) channel model for macrocell environments was simulated with angular spreads (AS) taken from measurement data. Simulation results showed that the performance improvement introduced by the Eigen-OSTBC scheme can be observed even without extensive numerical analysis as traditionally expected. It is also showed that the received signal is highly correlated with the original transmitted signal.
