Abstract

This paper describes the system architecture, design methodology and subsequent FPGA mapping of a millimeter wave digital baseband for wireless communication in the 60GHz spectral band. The baseband is designed to be compliant with the 802.11ad Single Carrier and Control PHY draft specifications and supports a data rate of 2.5Gbps at the physical layer. The demanding throughput and latency requirements are achieved with a parallel implementation. However, due to limited capacity of the FPGAs present in our prototype platform and complex partitioning requirements, only a scaled down version of the full single carrier baseband that operates at 1/10th the throughput of the specification could be mapped. A minimal real-time hardware MAC was also incorporated and coupled with a 60GHz RF beam-forming front-end to demonstrate file transfer between two independent FPGA prototyping systems. A system throughput of 59Mbps was achieved at the application layer using π/2 QPSK modulation with a 13/16 LDPC code rate.
60GHz多GBPS单载波数字基带设计及FPGA实现
本文介绍了60GHz频段毫米波数字基带无线通信的系统架构、设计方法和后续FPGA映射。该基带设计符合802.11ad单载波和控制PHY草案规范,并支持物理层2.5Gbps的数据速率。通过并行实现可以满足苛刻的吞吐量和延迟需求。然而,由于我们的原型平台中存在的fpga容量有限和复杂的分区要求,只能映射以规格吞吐量的1/10运行的完整单载波基带的缩小版本。还集成了一个最小的实时硬件MAC,并与60GHz射频波束形成前端相结合,以演示两个独立的FPGA原型系统之间的文件传输。采用π/2 QPSK调制和13/16 LDPC码率,在应用层实现了59Mbps的系统吞吐量。
