Abstract
This paper addresses an uplink system configuration for an Industrial Environment, in addition, a novel robust and low-complexity space time code is proposed. Based on channel modelling of Quadriga which follows a geometry-based stochastic channel modeling approach, the proposed space time code is applied in the uplink of an industrial communication system. Simulation results show that the proposed code outperforms Alamouti code for Industrial Automation. The bit error rate (BER) performance demonstrates that the achieved coding gain for the proposed code is higher than Alamouti code. Furthermore, a low complexity decoder based on minimum mean squared error is designed at the receiver side. The proposed space time code is designed basically for increasing the reliability and robustness in industrial communication systems where BER of 10–9 is demanded. The proposed code provides superior performance against the state-of-the-art space time code systems.
