Design and implementation of single-carrier MIMO transmission with frequency domain equalization

A multiple-input multiple-output (MIMO) single-carrier frequency domain equalization (SC-FDE) testbed which can emulate a practical broadband system is described. A scheme combining space-time transmit diversity with SC-FDE was implemented and evaluated on the testbed. After the hardware configuration, software algorithms incorporating the space-time block coding and decoding, synchronization, channel estimation and frequency domain equalization are explained, followed by some field measurements which validating our design and implementation. It is showed that this software reconfigurable testbed is flexible and convenient to evaluate different system performance in kinds of wireless environments.
