Abstract

The MIMO-STBC system based on the generalization of the Alamouti scheme has been widely applied in practicing due to their advantages in terms of band width, coding and decoding, achievement in diversity gain with linear processing in receivers or suitable for compact mobile machines which are difficult to implement for multiple antennas that have been researched extensively in linear situation. Some evaluation of nonlinear distortion effect caused by HPA have implemented in [11], [12] but the determination of the relationship between the nonlinear parameters with system parameters is not specified. This paper provides an experiment formula for calculating the SNRD (Signal-to-Noise Degradation) according to the dd (dd: Distance Degradation) in the MISO 2×1 STBC system.
