Design and FPGA implementation of wireless baseband modem for WiMAX system based on SDR

الملخص EN

This paper present a design and implementation of Wireless modem with 16-QAM modulation, convolution and differential coding based of SDR using MATLAB system generator model, for WiMAX applications.

The key difficulties used in the modulation schemes for WiMAX design, as mentioned by IEEE 802.16 standard, needs ample hardware if all the modulation schemes and code rates have to be designed on FPGA.

The implemented modem performance has been checked using the error rate calculation as an indicator, with different channel noise environments.

The results of resource estimator showed the use of an appropriate number of slices, and other resource of FPGA for the completion of this design and this is encouraging for the use of this design in a variety of other applications of wireless communications.
