In this paper, we propose an analysis of the wireless multipath channel in square-shaped environments. By considering propagation characteristics of the wireless transmission such as path-loss and reflections in this environment, we provide a wireless multipath channel generator that depends on transmitter and receiver position and can be easily integrated into numerical simulations. In order to demonstrate the validity of the proposed simulation framework, we provide a numerical analysis of the spatial channel correlation between two receivers over random positions of the transmitter in a defined area, which can be also treated as a performance indicator. Interestingly, the results show that the region where the transmitter is positioned has a large impact on the channel correlation. To corroborate our channel simulator, a blind energy detection based spectrum sensing has been implemented, where we show the …
