Configurable baseband designs and implementations of WiMAX/LTE dual systems based on multi-core DSP

Abstract

This paper deals with configurable baseband designs for IEEE 802.16m and TD-L TE systems. Thanks to the similar frame structures and signal flows between these two standards, the configurable designs and implementations of WiMAXlL TE dual system are feasible. 8y 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.

Design and implementation of an OFDMA-TDD physical layer for WiMAX applications

“…In particular, the most attractive PHYs are those that for 802.11n and 802.16e [22], and a 802.16m and LTE downlink implementation [23].…”
