Abstract :
Strategically selecting the location of antennas in sparse arrays can dramatically improve a communication system´s resilience to both multipath fading and interference. By formulating the information theoretic capacity of a system employing an antenna array (both SIMO and MIMO) for a specified channel and interference model, we show how to optimally choose the locations of each antenna in both a 1D and 2D space to maximize mutual information given prior constraints on the antenna positions.
