Research and Design of 5G System Based on Heterogeneous Computing Platform

由于数字信号处理复杂度高原因,5G无线通信系统通常基于专有ASIC芯片进行设计,一定程度上限定了其灵活性和扩展性。软件定义无线电的思想是将无线系统单元从功能固化的硬件迁移到通用计算硬件,通过编写软件实现特定的信号处理功能,达到了平台开放的目的。基于异构计算平台实现的5G无线通信系统,通用的硬件平台能很好的支持灵活部署,提高计算资源利用率。随着5G演进,eMMB和uRLLC场景对于高吞吐和低延时进一步提出要求,专有芯片成为了发展瓶颈,基于提供的ARM、DSP和FPGA组成的5G平台,不仅具备灵活性,扩展性,开发周期短特点,而且具备较强的计算性能能力,满足各种5G无线应用场景性能需求。

Due to the high complexity of digital signal processing,5G wireless communication systems are usually designed based on proprietary ASIC chips,which limits their flexibility and scalability to a certain extent.The idea of software defined radio is to transfer the wireless system unit from the functional hardware to the general computing hardware,and to achieve the purpose of platform opening by writing software to realize the specific signal processing function.In this paper,the 5G wireless communication system based on heterogeneous computing platform is implemented.The general hardware platform can well support flexible deployment and improve the utilization of computing resources.With the evolution of 5G,eMMB and uRLLC scenarios put forward further requirements for high throughput and low latency,and proprietary chips have become the development bottleneck.The 5G platform composed of ARM,DSP and FPGA provided in this paper not only has the characteristics of flexibility,scalability,short development cycle,but also has strong computing performance.Meet the performance requirements of various 5G wireless application scenarios.
