In mobile communication, a less explored technique to mitigate fading effects is based on the physical parameter of the transmitter by varying the physical dimension of the transmitting antenna. This paper deals with a self adaptive system to eliminate severe fading effects in different multi antenna set-ups by adaptively updating the effective aperture of the transmitting antenna. The system changes the effective aperture of the transmitting antenna to adapt to a previously set system parameter. The authors consider here Single Input-Single Output (SISO), Single Input-Multi Output (SIMO), Multi Input-Single Output (MISO), and Multi Input-Multi Output (MIMO) system with three different modulation schemes - BPSK, DPSK and QAM.
