In this project, an array signal processing test-bed is constructed. This test-bed is named as the Versatile MIMO Antenna Processing System (vMAPS). vMAPs is a high-end data acquisition and processing system that combines the low cost and familiarity of a standard PC environment with high performance PCI products from Interactive Circuits and Systems Limited (ICS) and third party DSP and data storage hardware. The vMAPS uses WinNT, Windows 2000 or Windows 2000 server operating system and the popular LabView software for GUI based control and display. With the integration highly advanced PCI and PMC bus boards and associated software, a wide range of high speed and high accuracy data acquisition, storage, demodulation and sensor array processing applications can be easily configured. In the project, experiments are conducted on Direction of Arrival (DOA) estimation, adaptive beamforming and space-time coding. Experimental results show that the system is working satisfactory.
