Abstract
Probability density function of array output Signal to Noise Ratio (SNR) for a Millimeter wave Multiple-Input, Multiple-Output system with Maximal Ratio Combining (MIMOMRC) is analyzed. Millimeter wave, as the name indicates, works on high 28, 38, and 72 GHz frequency bands yielding reduced antenna size. These antennas with sizes typically in the range of millimeters are therefore integrated on-chip. They can also be steered to achieve enhanced directivity and channel capacity. Directional antennas are realized using beamsteering in millimeter wave communications to achieve very high data rates and also high capacity. The data rates are reported to have increased by around 40 times as compared to off-chip antennas. An important statistical parameter to determine channel capacity of any millimeter wave cellular link is the probability density function. In this paper, probability density function, cummulative distribution function and outage probability of output Signal to Noise Ratio is mathematically analyzed for a Millimeter wave Multiple-Input, Multiple-Output system which incorporates beamsteering and Maximal Ratio combining.
