In this paper, a technique for realizing a low condition number channel
matrix for line-of-sight (LOS) multi-input multi-output (MIMO) transmission
scenario is presented. The main idea behind the proposed work is to make use
of a change in carrier frequency of adjacent transmit antennas to increase
the MIMO capacity gain without requiring any additional bandwidth. We derive
the criteria for the maximum capacity in terms of difference between carrier
frequency for adjacent transmit antennas. The performance of this technique
is investigated with the help of simulation results.
