| Abstract(in English) | Recently, a MIMO (Multiple-Input Multiple-Output) communication system which realizes large channel capacity has been attractive in wireless communications. Spatial correlation and mutual coupling among array elements affect MIMO system performance, especially for an array of closely spaced elements. The conventional MIMO channel capacity is defined by normalizing averaged SNR at a receiver. However, when we evaluate the mutual coupling effects on a MIMO system, we cannot ignore changes of path-gain as a function of array spacings. Link capacity including path correlation and received power variation should be evaluated in this case. In this report, we formulate the channel capacity and link capacity by using both of spatial correlation and mutual coupling matrix, and evaluate the effects of mutual coupling on a 4 × 4 MIMO system of a dipole receiving array in Rayleigh fading environment. |
