摘要

本文讨论了IEEE 802.16m和TD-LTE系统的可配置基带设计。由于两种标准之间具有相似的帧结构和信号流,因此WiMAX/LTE双系统的可配置设计和实现是可行的。通过比较两种系统的信号处理流程,提出了一种既可以配置为基站也可以配置为移动基站的通用架构。利用德州仪器(TI)的多核DSP、赛灵思FPGA、ADC、DAC和RF收发器完成了实现,并提供了实时视频演示。

Configurable baseband designs and implementations of WiMAX/LTE dual systems based on multi-core DSP
This paper deals with configurable baseband designs for IEEE 802.16m and TD-LTE systems. Thanks to the similar frame structures and signal flows between these two standards, the configurable designs and implementations of WiMAX/LTE dual system are feasible. By comparing the signal processing flows in both systems, a generic architecture, which can be configured as either a base station or a mobile station, is proposed. A realization using Texas Instruments (TI) multi-core DSP, Xilinx FPGA, ADC, DAC and RF transceivers is accomplished and a real-time video demo is delivered.
