Abstract

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.
