Abstract: Several studies have been conducted on the effects of radiation on the human body. This has been
especially important in the case of radiation from hand held mobile phones. The amount of radiation
emitted from most mobile phones is very small, but given the close proximity of the phone to the head
it might be possible for the radiation to cause harm. The suggested approach involves the use of adaptive
active control algorithms and a full space-time processing system setup (i.e. multiple antennas at
both the transmitter and receiver side or MIMO), with the objective of reducing the possibly harmful
electromagnetic radiation emitted by hand held mobile phones. Simulation results show the possibility
of using the adaptive control algorithms and MIMO antenna system to attenuate the electromagnetic
field power density.
