Analysis of Correlation on Performance of Golden Code Based on HF Watterson Model

摘要

HF communication is one of the primary means of long distance communication. In recent years, because of its small transmission power and strong ability of anti-interference, it is widely used in various communication fields. The space-time coding has also been extensively studied to increase the channel capacity of effective technology. The Golden Code, a full rate and full diversity code for the 2×2 coherent multiple-input multiple-output(MIMO) systems. This outperforms all previous know codes. This paper proposes an idea of which Golden Code is applied to HF communication. However a basic assumption in studying Golden Code is that the channels between different transmit antenna and different receive antenna pairs are independent, but it can not always hold in real-life. This paper introduces the system model about Golden Code. An expression for Golden Code is derived under correlation channel based on Watterson model. Finally, the analytical results are verified through our computer simulation for Golden Code.
