In the course, you are supposed to implement some typical communication systems with a DSP-based wireless system.

Plateform: – Spartan 6/OMAP-138 coprocessing kid

– Produced by Avnet

– FPGA: Xilinx Spartan 6

– DSP: TI 6000

– CUP: ARM processor DAC/ADC module:

– 40MHz

– 12bits/10bits RF module: Maxim for WiMax system The purpose of the experiments is to let you know how a

wireless communication system actually works.
