Narrow-Band Channel Simulator Based on Statistical Models Implemented on Texas Instruments C6713 DSP and National Instruments PCIE-6259 Hardware

摘要

Hardware channel simulators are desirable to test baseband processing units for performance analysis, and also for system design and verification. Here we present a narrow band channel simulator implemented on a Texas Instruments C6713 floating point digital signal processor and a National Instruments PCIe-6259 multi channel card. The implementation methodologies, strategies and models suitable for finite precision data representation and the related hardware and software are discussed. The mathematical and statistical models used to implement the channels are also presented. We implement various channel models for narrowband applications with bandwidths varying from 4 kHz to 1 MHz in base-band. Finally, we present some real world experimental data using the hardware channel simulator, and verify the results.
