A REAL-TIME PRE-MIMO-LTE SOFTWARE RADIO TESTBED

摘要

The contribution describes the implementation of a MIMOrn(Multiple Input - Multiple Output) OFDM (Orthogonal FrequencyrnDivision Multiplex) online demonstrator with certainrnparameters for the 3rd Generation Partnership Projectrn(3GPP) Long-Term-Evolution (LTE) system, by employingrnour scalable multi-standard Software Defined Radio (SDR)rnTestbed [1][2], which is built up with Sundance modularrnhardware components [3]. In comparison to prior MIMOrntest-bed installations, the entire digital signal processing isrnachieved in real-time using Texas Instruments DSPs and XilinxrnFPGAs. It indicates that ourMIMO Testbed structure canrnaccelerate the development and evaluation of the techniquesrnfor the next generation wireless communication systems.
