The third generation partnership projects spatial channel model has been attracting great and wider interests from the researchers for a stochastic channel model for MIMO systems and multi-antenna-based multi-input multi-output (MIMO) communications as they become the next revolution in wireless data communications. MIMO has gone through the adoption curve for commercial wireless systems to the today’s situation, all high throughput commercial standards, i.e. WiMax, Wi-Fi, cellular, etc., have adopted MIMO as part of the optional. This paper is to present our investigations of the behaviors of the MIMO Ultra-Wide-Band-Impulse Radio (UWB-IR) systems, which will contribute to optimal designs for the low-power high-speed data communication over unlicensed bandwidth spanning several GHz, such as IEEE 802.15 families. We have developed and analyzed three no coherent transceiver models without requiring any channel estimation procedure. The massive simulations are made based on the established models. Our investigations show that the Poisson distribution of the path arriving will affect the signal-noise ratio (SNR) and that for the Nakagami distributed multipath fading channel the “m” factor, together with receiver number, will impact on the SNR of the MIMO UWB-IR systems.
