The improvement in channel capacity hailed by MIMO systems is directly related to intricate details of the wireless channel such as the degree of correlation between the multiple channels established due to a MIMO configuration. Capturing these details in real time emulation systems becomes absolutely essential to validate theoretical results in a controlled setting. This paper presents methods to achieve significant improvements in speed and complexity for real time channel emulation maintaining high resolutions in time and frequency. In particular, this paper presents a frequency domain emulation technique that reduces add/multiply operations by 54% compared to conventional FIR emulation. A comprehensive complexity analysis is performed to compare the complexity of different techniques.
