Abstract
In this paper, we present a real-time implementation of an OFDM hardware platform. The platform
is based on HW blocks that can be put together to configure a wireless system based on OFDM modulation.
The platform can be easily upgraded to test pre-coding cooperation algorithms.
We
evaluate the platform to
implement a diversity Alamouti 2×1 MIMO scheme wireless system. The testbed is implemented using Field-
Programmable Gate Array (FPGAs) through Xilinx System Generator for DSP. Blocks for time-domain
synchronization and channel estimation are key components necessary in transmission system that require
good time synchronization and channel estimation for efficient demodulation
