摘　　要：信息本质上以能量和熵的形式在通信系统中流动,类似于传统热机中的能量流动过程。结合热力学卡诺机模型和经典香农信息论理论,建立了一个广义的热力学(multiple input multiple output,MIMO)通信系统模型,对大规模天线通信场景下使用前向纠错码的信道容量进行分析。利用通信系统中存在的自由度和熵的概念,推导了热力学模型下的广义信道容量,并对信道容量与噪声自由度及编码开销的关系进行验证仿真。仿真结果表明,所提出的热力学信道容量与香农信道容量是一致的。Similar to the energy flowing process in traditional heat engines,information could be considered to flow in communication systems with the form of energy and entropy.Combining the thermodynamic Carnot machine and the classical Shannon information theory,a generalized thermodynamic multiple input multiple output(MIMO)communication system is established to analyze the channel capacity using forward error correction codes.Based on the concepts of freedom and entropy in the communication system,the generalized channel capacity is proposed under the thermodynamic theory.Furthermore,the relationships between the proposed channel capacity and the noise freedom and coding overhead are derived and simulated.Simulation results verify that the proposed channel capacity is coincident with the classical channel capacity.
