Abstract
Multiple input multiple output (MIMO) is a technology that enhances wireless systems capacity, data rate, and coverage by utilizing the spatial diversity provided by multiple antennas. However, these benefits come at the expense of increased computational complexity. Implementing a broadband MIMO wireless communication system in a real-time testbed is a challenging task, entailing numerous pitfalls. This paper presents several implementation aspects of a real-time MIMO testbed based on the mobile WiMAX standard. The focus is mainly laid on the bit-intensive baseband digital signal processing at the receiver.
